Hi! I’m creating the museum of art in VR. Since my main platform is Samsung Gear VR I’m very careful with resources. For now I’m using basic cube for canvases and noticed my material with painting is spreading to all sizes of cube. The question is will it slow the performance and should I change it to meshes with several material ID’s and apply textures to one side using it?
Will it slow the performance if textures is used on every side of cube
More material ids - more draw calls, slower performance.
I think you can create simple black&white texture mask of not painting part according to cube UVs (2nd channel) and use it to fill that part by some solid color in material. So, simply Lerp painting part and color by that mask with 2nd UVs channel.
