iToo Forest disappears when starting VRAY IPR
« on: April 12, 2017, 02:59:37 PM »
Hey guys,
everytime I start VRAY IPR (Interactive) Mode my Forest objects disappear. They do render but are no longer visible in my viewport, so I can't move them around. Is this normal behavior? Or have I missed some settings?

System: iToo Forest 5.3 + Vray 3.50.04 + 3ds max 2017

Regards
Olaf

Hi, yes this is the normal behaviour actually.

V-Ray IPR uses a mixed mode between viewport and render, which is not supported by Forest. Our plugin generates a different set of items for each mode, and only one of them can exist at time.
Unfortunately there is not a simple solution to fix that, but is in the wishlist for next versions.

By the way, same problem happens with Corona Interactive.

Any update on this? Can you at least replace the forest pro objects in viewport with pyramids or boxes? Not knowing the name of many different forest objects makes it difficult to select and update interactively. Thanks

We have plans to solve this limitation in Forest 6, which is actually in development.
I tried a quick fix for the current Forest, but it caused undesired side effects, and was discarded.

The problem is not to display point-cloud or boxes, but that the scattered items are completely different. You may have 20k items on viewport and 1 million on render, so we must generate and keep a different set of items for each mode.

Thanks for working on this. If anything, could you please keep the viewport display on even if it doesn't represent the total geometry? Just so we can easily select and generally set up camera angles while rendering interactivity? Thanks again for your support!
