Trouble with chroma transparency. (Solved) I'm trying to get a chroma transparent texture to work with the new Stamp feature without success. I'm trying to build a 'forest' by scattering a tree over a terrain. So, the whole 'forest' is one object, and each 'tree' should be a stamp. I was able to get the stamping/billboarding to work properly, with the exception of the transparency. I was able to get chroma transparency textures working in rF1. However, it seems that the same settings: Chroma checked, set to the proper color ( (255,0,255) in this case ), and Source/Destination left at One/Zero. I even tried Source/Dest. at SrcAlpha/InvSrcAlpha, but that seemed to make all of the textures additive (becoming a white 'blob' on screen). I tried just T1, which made the whole 'forest' disappear. I've also tried 'T1 Stamp Vertex', 'T1 No Shadows Stamp Vertex', and 'T1 Stamp Vertex Alpha Test'; each of which produces the same result (no transparency). So, am I missing something someplace? Does the functionality not work? Or might this possibly be another 'bug' with the plugins (using the Max2010 plugins in Max2011)? Thanks again in advance for everyone's support!
