As implied in subject line, my itoo scattered plants dissappear arbitrarily during rendering an animation.
I start rendering the animation and at frame 17 all my plants dissappeared in render. If I restart the render on the same scene without restarting 3ds Max it no longer renders the plants.
If I restart Max and restart rendering it again starts rendering plants but this time they dissappear at another frame (10, 21...)
https://www.dropbox.com/s/0xk1ynz7buao7pq/Anim2.zip?dl=0I send you the dropbox link to the file above. I built the file over a sample provided in your wabpage. The grass sample. I added similar plants next to it. Moved a stereo camera around the plants. As I've said it starts rendering and plants dissappear after a few frames. Also attached frames 19 and 20 of the animation render.
On the Mental Ray error window, there is also an error about template objects (those named like...) _forest_template_Curved Plane etc.
Error states that these transformation matrix can't be created for these objects because they have zero scale. (xyz).
I get rid of the error by hiding those.
There is a stereo camera in the scene which also determines the plant limits. I tried turning off camera limits and distance falloff.
Best regards
