PaperFlipbook SetColor sets a wrong color in android?

Hi,

As a part of a Blueprint I have a Timeline to change the color of a PaperFlipbook over time and destroy it as you can see in the attached screenshots.[Blueprint][1]

It does work in the simulator and on a Win64 build but it does not work on Android! Tested on a Samsung Galaxy S3. When the timeline starts, my sprite turns black. In PC and simulator I can see how it starts from red and ends in black (as expected)

I have tested with HDR on and off and it does not change anything. The other parts of the game works perfectly.

Any advice?!

EDIT: Actually I now see there is a color applied but it is BLUE instead of RED !

I do not know if its a bug or I’m missing something here :frowning:

Hi Dredok,

This was a bug in how the color was being interpreted in the shader, causing an unnecessary swizzle. I’ve fixed this in CL# 2275428, which will be in 4.5. Sorry for the inconvenience.

Hi Dredok,

Yeah, the github commit I linked above is the checkin to the main branch.
