Re: vertex colors vs bitmap texture - cost/performance considerations?
Vertex color is always faster. Always. But, there are some limitations that you already pointed. What can be a little more expensive, is how you use the vertex color data, for example, alphas. But still faster than textures. -
Re: vertex colors vs bitmap texture - cost/performance considerations?
I'm also using vertex color a ton on mobile. It's a huge savings there. But just for customization/masks it can't be beat, using a texture for masks is a waste since you would often need unique non-overlapping UVs (2nd uv channel adds to the vertex count). Also if you're only using one channel of the bitmap, that's a… -
vertex colors vs bitmap texture - cost/performance considerations?
just wondering if there's any general rule when it comes to the performance/memory overhead for using vertex colors over a bitmap in materials. there's currently a single 2048 texture that i'm using in a hair material. it contains two 8bit/greyscale channels, one for a painted texture overlay that supplies strand detail,… -
Re: vertex colors vs bitmap texture - cost/performance considerations?
thomasp talked about his process some in his sketchbook, some more great examples in there too, inspirational work... http://polycount.com/discussion/83970/sketchbook-thomasp/p1 Greyscale isn't a channel, at least in game art usage. You can store a texture in two channels (grey + alpha) but the graphics card will always…
