Worked: Never
**Short description of error**
Output of various blend modes is different depending on whether byte or float image is blended
Right now I am not sure which result is correct (or if any)
In example file Blend is set to Linear burn with brush strength of 0.5 (I assume this will give brush pixels alpha of 0.5)
**Exact steps for others to reproduce the error**
# Open file
# Paint both textures with pre-set brush
Result is different
