dropped to 15 version - problem with alpha channel + occurrence in sequences of black frames when rendering animations

same here. I did a 300 frame animation and there were 10 black frames in the middle - very odd.

Are these frames rendered OK when you render just one frame that is rendered black in animation rendering?

correct Jim, just random black frames which otherwise would render normally.

Separately, I'm trying to do a camera map with octane. Is this possible?

+1 It is interesting that the sequence of black frames is saved... if I remove the sequence of images and re-render will have black frames will be in the same order

response - LINEAR - save *PNG

This is a bug in 3ds Max' Bitmap. As soon as the image buffer having non-1.0 gamma is loaded into Bitmap - Max screws up alpha during saving a PNG from Bitmap window.
I've found some workaround for this, will be OK in next version. So far as I suggested before - use 1.0 gamma in Octane imager.

A left image is saved when a buffer of Max Bitmap is filled by 2.2-gamma image, and the gamma of a Bitmap is set to 2.2. A right image - all the same but the Bitmap buffer is filled by 1.0-gamma image and the gamma of a Bitmap is set to 1.0.
In the first case - Max screws up the correct alpha value "0" and turns it into "255".

Guys I can't reproduce it on my scenes. Could somebody who has this issue give me the scene?

the random animation (random animation offset) function coming with forest pack pro does not work anymore.
all forest instances start at the same frame now.
I am sure it has worked in karba version, did a big animated project using random animation mode back then.
I hope you can bring that back again.
tnx

If everything is OK now with black frames to everybody - I'm going to release a next version...
Because all is OK on any of my scenes as I wrote, can't reproduce on any of them...
