Billboard Z Depth issue

[J. Baker]

Anyone else have a Z depth issue using Billboards? I made (AddBillboard()) 5 Billboards in the group but the farthest tree in that group overlaps the closer trees. It shows up smaller than the closer ones due to its depth but just over laps the others. Will look into it more but was just wondering if anyone else noticed this or had this issue.

Try this:

Code: Select all

SetMaterialAttribute(yourbillboardmaterial,#PB_Material_DepthWrite,#True)

Thanks. It works but kills or does something strange to the alpha information of the image.

I'm not sure what is the problem with your alpha so keep the previous and add these:

Code: Select all

MaterialBlendingMode(yourbillboardmaterial,#PB_Material_AlphaBlend)
MaterialCullingMode(yourbillboardmaterial, #PB_Material_ClockWiseCull)
SetMaterialColor(yourbillboardmaterial,#PB_Material_DiffuseColor,RGBA(255,255,255,255))
SetMaterialAttribute(yourbillboardmaterial,#PB_Material_AlphaReject,128)

Thank you! #PB_Material_AlphaReject works but it is not as smooth as #PB_Material_AlphaBlend.

This is what it does with #PB_Material_AlphaBlend. It kind of uses the alpha channel but then it doesn't as you can see it blocks the background tree. Using a 32bit PNG image.

All the 5 lines are needed for the tree material. Sorry if I wasn't clear enough. Try it, that should work.

Oh, I did try that first and it didn't make a difference, so I just use the one.
