Trouble with UV Mapping Blender => Unity 3

For some reason I am getting nasty grey edges around the edges of rendered 3D models that are not present in Blender. I seem to be able to solve the problem by reducing the size of the UV coordinates ...

XNA UV Mapping flipping the Texture every second time

I am making a tile based game. Recently I moved to drawing tiles as primitives to speed up things and also allow for easier lighting (Vertex Shader). I then took it a step further and made some ...

Drawing a textured triangle with CPU instead of GPU

I understand the benefits of GPU rendering and such, but for a certain limited application I need to render textured triangles purely using CPU. I've built a 3D engine capable of object handling, ...

Programmatically determine UVs by rotating a plane along X axis

I'm having a math brainfart while trying to solve what might be a simple problem. I've got a plane in 3d space (it's actually the face of a 10-sided die): Coordinates [x,y,z]: Point_top = [0,0,1] ...

Interactively edit UV mapped, textured mesh in Cinema 4D without distorting texture?

I'm fairly new to Cinema and I'm building a rigged flat (2d) character out of illustrated pieces. I want the meshes to have an efficient number of polys but sufficient resolution where they'll bend ...

What to do to UV coordinates, when swapping Z/Y coordinates (axis) of the geometry?

In my Maxscript exporter I have the ability to flip the Z/Y axis by simply swapping the Z and Y co-ordinates. When swapping the axis this way, what is the correct thing to do to the UV coordinates? ...

Is there any difference between storing textures and baked lighting for environment meshes?

I assume that when texturing environments, one or several textures will be used, and the UVs of the environment geometry will likely overlap on these textures, so that e.g. a tiling brick texture can ...
