TsLastDetail

Hi, made a simple object today with 5 level of details, in which on the last ive set it to export as "tsLastDetail".
Works fine in the ShowTool Pro, as in the last detail is a sprite rendered from the first detail - but in TGEA the item just disappears?
Is this a TGEA bug, or something no longer supported?
Regards

Just wondered if anyone has taken a look at the code, or what might be broken?Regards,

First the TSShapeInstance::snapshot() function isn't fixed to work with changes in GFX and lighting. So it cannot capture the impostor images properly.
Second the code used to generate the final impostor image from two snapshots incorrectly blends them... resulting in a very bad looking silhouette.
Third the alpha fade between the billboard and geometric LOD levels is not working. This makes transitions a hard pop.
Finally TSLastDetail is much slower than it could be... i'd be surprised if rendering these billboards this way is that much of a win.
We'll have a complete rewrite of TSLastDetail in the Forest Kit... no ETA on that to announce just yet.
