I need to sampler lightmap with uv2, I need to set submesh.materialDefines.LIGHTMAPDIRECTUV=2 to achieve my goal.
After I load Mesh, submesh’s materialDefines is undefine. I find bbl firstly creates materialDefines for submesh after isReadyForSubMesh, when should I get subMesh’s materialDefines and update it?
You should never access it directly like this
Why not setting the coordinates of the texture directly ?
Ohh，Thank you, I don’t know this api before
