I just tried one or two random examples in 2.92. Seems to work OK.

Looks OK in Cycles. I think this is an Eevee limitation -- look at the [description of Alpha Blending](https://docs.blender.org/manual/en/latest/render/eevee/materials/settings.html) for more details. I tried changing a few materials to Alpha...

[Here](https://github.com/johnzero7/XNALaraMesh/files/6463603/eevee_alpha_blend_limitations.blend.zip) is a very simple example to illustrate the problem. As the docs say, Eevee’s Alpha Blend feature is implemented on a per-object basis. So if one object is both...

Also works fine with 2.93.

Probably means what it says.

For what it’s worth, I used this [formula from StackExchange](https://math.stackexchange.com/questions/180418/calculate-rotation-matrix-to-align-vector-a-to-vector-b-in-3d) to compute a lookat matrix. Note that you will get a divide-by-zero condition if the direction is exactly opposite to...

I think Cairo always expects B to be in the least significant byte, G in the next byte up from that, and R in the byte up from that. In...

I added some XCB hooks in my [pure-Python binding for Cairo](https://github.com/ldo/qahirah), and more recently was able to make use of those hooks to create a [binding for `xcffib`](https://github.com/ldo/qahirah_xcffib). This also...

Suggestion: implement your own Bézier rendering algorithm. The De Casteljau construction is not hard to implement.
