I found this odd bug. When using custom geometry type, the UV of the custom geo isn’t transferred if the particle source are from Realflow. If the particle source are from Pflow or TP then the UV is transferred just fine. I tried to load the realflow particles through PRT and it acted just the same.
Frost ver - 1.1.2.44769
Tested on MAX 2011 and 2012.
Attached file with bin files as sources and also a pflow setup for comparism.
The BIN file already contains a UVW channel 1 (TextureCoord) from RealFlow, so Frost is assigning it to each particle, thus overriding the UVs of the source geometry (the box). The simplest solution is to add a UVW Map to the Box and set it to channel 2, then switch the Checker map to 2 - the Frost + BIN files setup will suddenly work.
If you drop a Mapping operator in the PFlow and check its “Show Map In Viewport” option, Frost will “lose” its mapping, too, for the same reason.
How did I figure it out? I used the Particle Data Viewer on a PRT Loader with the BIN files to peek inside the data!
