Is it possible to sample and then store / fix a color to use in a material?
In other words, can you sample skin colour once and use that color as the material for (say) elf ears?
I think it can be done ‘live’ but I was hoping to avoid colour changes as the user moves around.
I’ve seen a stack overflow question where the answer appears to suggest that this is not possible (‘The texture data is stored on the GPU, and there is no way in Spark to read this data from the GPU to the CPU for scripting purposes’ - from Spark AR Studio: Is it possible to get the color of a screen pixel from script? - Stack Overflow).
Thanks for any help.
