Structured Buffer Merge (Rendering Pain Day)

[samzanemesis]

I've merged the Structured Transform Buffers change I had queued, this will be the equivalent of Pain Day for rendering

This also means our base addon shaders are now compiled to use the new Shader API base

Here's what you need to know:

• Whole transformation system has been refactored, this should give you also better performance
• All your custom shaders will need to be recompiled
• Editor stability should be improved
• Objects with over 2048 transforms per call like Cloth will render fine now, you can bake cloth in your maps
• Some textures might appear with a checkerboarded pattern when the material is recompiled
• Specular occlusion is unavailable on the base shader, your smooth objects with the Standard Shading Model might get overbrightened on dark areas, this is being fixed as soon as possible
• This is also the case for High Quality Reflections and debug views, which will be added to the new shader API

Attach an issue to any problem that could be related to these changes and I will have a look at it as soon as possible
