I point out what I noticed while testing my custom panel.
That is about TVPaint's composite mode "multiply".
Can you solve the problem that is not displayed when exporting with transparent background?
Attach the image that compared to Photoshop.
Thank you.

+1 .

I have often noticed this odd behavior of TVPaint with layers that are in multiply blend mode . It's not possible to export them with transparency.

But it is possible with Photoshop . (and also Autodesk Sketchbook , Artrage, Gimp). So this should be possible with TVPaint , too, I would hope.

This issue with how TVPaint applies blend modes such as Multiply goes back to another issue (from 2014) which never had a response from anyone at TVPaint, in this thread:

Peter Wassink summed up the issue in the last post of that thread:

this issue... when exporting images with layers set in blend modes (other then Color) ...
I'm just wondering about the logic and desirability of the current behaviour
[in TVPaint] ?
The advantage of a "what you see is what you get" behaviour [as in Photoshop] is probably obvious,
but what is the advantage of the current behaviour in TVPaint? I suspect it has to do with some deeper level of logic?
