I have finally managed to create working billboard trees thanks to gMaterial tool but I have a strange issue. When I clone and then attach everything to one object, the trees at the front become transparent but only if there is another tree behind. So when I rotate around, the tree at the front become transparent when another tree appears behind. Do you know what might be wrong?
Sounds like your using alpha transparency, so you get alpha sorting issues. You have the offset number in the material setting, or you could use chroma blending, which is also better for performance.
Thank you, chroma blending works perfect . I have another question, is there any possibility to see the texture on both sides for non billboard plane?
I would suppose that it is deactivated for billboard objects, where the polys always face to the viewer anyway, so it is useless in that case. Try another shader.
Thanks, I changed to different shader ind it worked but I prefer billboards anyway. I have another strange issue, my plants seems to be very dark but when I come closer they suddenly get some light/color. The same happens when I turn my view towards the sun, do you know what might be wrong? As per below example, the bush at the first plan is the same as on the far plan and the brightness changes depends how close I am to the object. I have done my albedos maps I think correctly so I don't know what might be wrong. EDIT: Problem fixed, I changed the shader to Bump Spec Map T1 Stamp Vertex and it is working fine
