[Bug] - Transparency in Masks Breaks Blend Nodes #14

Closed Synthoid closed 1 year ago

Synthoid commented 1 year ago

When a surface output using transparency is connected to a Blend node's mask input, the blend node breaks and produces a malformed output. This was seen in v 1.0.7.

I was able to get around this using a Color Replace node and setting all other colors to black. Disabling that option will again produce malformed blend outputs.

Error: image

Expected: image

To further clarify, my expectation is that transparent or clear pixels would be treated as black during mask operations.

Okay, so it seems like it samples only the RGB channel. I'll change it to multiply alpha too in the next version. Thank you.

Multiply alpha in blend node is added in 1.0.8.
