Home-made Render Farm

https://www.blender.org/manual/render/output/video.html

An easy way to get multiple machines to share the rendering workload is to:

Set up a shared directory (such as a Windows Share or an NFS mount)

Un-check “Overwrite” and check “Placeholders”

Start as many machines as you wish rendering to that directory – they will not step on each other’s toes.

Dropbox would make this super easy to do. Each computer has Dropbox installed along with Blender. Have it render directly to the Dropbox\blender\YourProject folder with placeholders. Each computer picks up a frame, renders it in its own time, and uploads it to the shared Dropbox. The slow ones falls behind rendering what they can, the fast ones skip ahead. However, that'll leave you with a bunch of frames that will still need to be rendered into video and I don't know how to do that yet. Adobe Premier is not cheap.

Could also be done with a home file server too:

How to Turn an Old PC Into a Home File Server

'http://www.howtogeek.com/190835/how-to-turn-an-old-pc-into-a-home-file-server/''

I set up a home blender render farm years ago as a proof of concept, but I hardly remember much about it. We got it working, but I never had a project that really needed the horsepower. I would use it today to render "cutscenes" because I miss FMV or game trailers I guess. It would be fun to know how to make my own home-made pixar-style "novelette".

I had an issue where I had applied both a cloth physics modifier and a subserf modifier at the same time to the same object and it wasn't rendering the movement out in the animation. To fix it, I had to make sure the cloth was above the sub serf in the listing of modifiers.

Bump mapping

https://www.wikiwand.com/en/Bump_mapping

Bump mapping[1] is a technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface although the surface of the underlying object is not actually changed. Bump mapping was introduced by James Blinn in 1978.

Normal mapping is the most common variation of bump mapping used.

Parallax mapping

https://www.wikiwand.com/en/Parallax_mapping

Parallax mapping (also called offset mapping or virtual displacement mapping) is an enhancement of the bump mapping or normal mapping techniques applied to textures in 3D rendering applications such as video games. To the end user, this means that textures such as stone walls will have more apparent depth and thus greater realism with less of an influence on the performance of the simulation. Parallax mapping was introduced by Tomomichi Kaneko et al., in 2001.

Parallax mapping is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface normal) and the value of the height map at that point. At steeper view-angles, the texture coordinates are displaced more, giving the illusion of depth due to parallax effects as the view changes.

CTRL + TAB while in edit mode to quick select vertex, edge, or face

Select faces and press S, Z, 0 to "flatten" them like to the floor/ground

http://www.ogre3d.org/tikiwiki/Blender+Exporter

The script OGRE Meshes Exporter converts meshes and armatures from Blender to OGRE file format XML / binary mesh / material file). It supports the export of

mesh objects with vertex colours, multiple materials, UV textures and blend modes,

a multitude of material properties, most notably: ambient, diffuse, specular, emissive, UV textures with and without alpha channel, vertex colours, normal maps, two sided faces,

keyframe animations of armature actions as skeleton animations,

keyframe animations of relative mesh shapes as pose or morph animations.

I also found an export guide specifically for Second Life:

http://wiki.secondlife.com/wiki/Mesh/Exporting_a_mesh_from_Blender

What are you exporting to? Like what is further down the pipeline?

And here is the Blender documentation:

https://www.blender.org/manual/data_system/files/import_export.html

Blender supports import and export to and from other file formats (e.g. OBJ, FBX, 3DS, PLY... etc).

To subdivide a plane:

1. Tab to go to edit mode

2. W to bring up menu

3. Subdivide

4. Press T to bring up the tool menu to select how far to subdivide it

AwesomeBump is a free and open source program written using Qt library designed to generate normal, height, specular or ambient occlusion, metallic, roughness textures from a single image. Additional features like material textures or grunge maps are available. Since the image processing is done in 99% on GPU the program runs very fast and all the parameters can be changed in real time. AB was made to be a new alternative to known gimp plugin called Insane Bump or commercial tool: Crazy Bump.

AwesomeBumpv4.0 for Win7/8 x32

https://github.com/kmkolasinski/AwesomeBump/releases/tag/Winx32v4.0

This is a little confusing at first, but you get used to it really quick. Click on the 'Diffuse' tab, and drag your image into there. At the bottom (make sure the Diffuse tab is active) click on the checkbox labeled "Basemap to others" and then click the button that says Convert N to H. From there you can tweak the settings

http://blenderartists.org/forum/showthread.php?364529-AwesomeBump-A-free-alternative-to-CrazyBump

http://blenderartists.org/forum/showthread.php?366395-AwesomeBump-3-0-beta-released

http://blenderartists.org/forum/showthread.php?366395-AwesomeBump-3-0-beta-released!/page4

In general, I have been doing the following:

Start AwesomeBump

Change to Diffuse Tab

Open a photo of, for example, a rock wall

Check the "Enable Preview" button

Hit the "Convert to N H" button

Un-check the Enable Preview button

Start tweaking.

Basically the processing should be as you described above.

Hope this clarified your doubts

How to apply Matcap materials for sculpting in Blender 2.71?

Simple out-of-the-box matcaps that work with cycles:

http://blender.stackexchange.com/questions/16339/how-to-apply-matcap-materials-for-sculpting-in-blender-2-71

Adding your own gets quite a bit more tricky if you want to stay in cycles. You can download ZMT files here:

Welcome to Pixologic's MatCap Library

http://pixologic.com/zbrush/downloadcenter/library/

But I don't think Blender supports them natively. Couple work arounds:

Might dig into the work-arounds at some point, but for now the quick and easy defaults should be more than enough for me.

FAQ:

Q: My background images won't show up after dragging them in.

A: Ensure that your view is properly aligned (press 1 on numpad to set view from front). You also need to be in orthographic (as opposed to perspective) view. You can toggle between ortho and perspective with 5 on the numpad. As an alternative to dragging the images in, you can press 'n' to open the properties panel, and add an image manually in the 'Background Images' section near the bottom.

Q: Pressing the numbers only changes frame/layer.

A: You need to press the numbers on the numpad. If your keyboard does not have a numpad, go into preferences and in the input tab check 'emulate numpad'.

Introduction to Dynamic Topology Sculpting in Blender

Learn how to use Dynamic Topology Sculpting in Blender

http://cgcookie.com/blender/2013/04/2...

The dynamic topology system in Blender allows for a much more organic, creative sculpting process. It gives you much more flexibility in not only how, but what you sculpt by not limiting you to the original starting basemesh.

When working with dynamic topology, Blender will automatically tessellate the mesh under your brush stroke to account for the detail needed. This gives you the ability to add detail anywhere you wish, create new forms, and work with a much more optimized polycount since the tessellations are localized.

Check out CG Cookie Citizen for more sculpting training: http://cgcookie.com/membership

I wanted to learn more with 3dsmax but I'm a beginner so should I learn the basics with blender? I'm going to assume a lot of general principles carry over.

>>24927

Yes, learning the art is essentially independent of the tools you use. You will, of course, know and come to adopt the methodology of whatever tool you do choose, but Blender is a good choice for a number of reasons.

What you learn in Blender will carry over to 3DSMax later.

In this Tutorial #35 I cover:

-After connecting an armature (bones) to a character mesh, the best way to make sure the bones properly control the correct parts of the mesh is by using weight paint mode.

-In this video I'll show you how to use weight paint mode to paint 'weights' (the amount of influence each bone has on each vertex) easily and quickly. I also cover how to *mask* parts of your mesh (in this case each block of the Minecraft person) to make it easier to paint only the sections you want.

Any good info on how to just get better at modeling and sculpting in general? I have a lot of tools down at just don't have good workflow and all that.

>>25521

And of course, by "3rd pic", I meant "4th pic".

Is it better to simply make models in blender or sculpt them in zbrush for some not so advanced 3D game?

>>25522

Ok makes more sense now.

>>25539

That pic is so aesthetic.

learning 3d modelling is just as easy as learning to paint

just do a lot of still life from references or actual physical things lying on your desk

do one every day

you're the best

Blender 2.7 Tutorial #36 : UV Mapping for Minecraft #b3d

''In this Tutorial #36 I cover:

Detailed instructions on how to add a Minecraft-like texture to a simple character:

-The process of marking seams, unwrapping, laying out a UV Map, Exporting a UV Map into Photoshop or Gimp.

-Painting a texture in Photoshopusing layers and the Dodge/Burn tool, Pixelating the texture using Photoshop's Mosaic Filter, saving .psd file and exporting to PNG, finally applying the texture back onto the character model in Blender

Remember, before UV unwrapping, go into object mode, then object menu > Apply > Scale

how the fuck would I do billboard sprites in blender.

i.e. a flat alphamapped quad that rotates to face the view in place. but can still be rigged to bones.
