Mask Object In Panda3D

Scripting Issues
1

I spend many time to mask my tree but lose

tree.setTransparency(TransparencyAttrib.MAlpha)
lowPassFilter = AlphaTestAttrib.make(RenderAttrib.MUnused,0.5)
tree.setAttrib(lowPassFilter)
tree.setAttrib(DepthTestAttrib.make(RenderAttrib.MLessEqual))

Can I mask texture in panda3D

Thank You

What texture format are you using for your tree? Are you sure that it has an alpha channel? Panda will automatically mask out the parts where alpha = 0 when you enable transparency; you don’t need to fiddle with AlphaTestAttrib or DepthTestAttrib.

My texture format is .bmp file
I think it has not alpha channel but How to try or it is impossible

thx :slight_smile:

Correct, .bmp format does not support alpha, at least not with Panda’s bmp reader. Save your texture in .png or .tiff format to keep the alpha.

Or you could use a separate grey scale map for transparency and put it in your modelling software
