i think i found another issue with RVTs:
i have a landscape with plenty of height-blended-layers (baselayer is alpha-blended). i write the resulting basecolor, spec, roughness and normal into the RVT-output.
in my lets say rock-material i use a RVT sampler to lookup the landscape RVT and do some distance based blending (using another RVT from the landscape that writes height).
now the problem:
all channels in the blend appear fine beside the basecolor one. the basecolor only shows the alpha-blended baselayer form my layerblend. all other channels (normal, spec, roughness) show up in the blend correctly (as in show the different e.g. normal maps of my different painted layers). only the basecolor shows nothing of my painted layers beside the baseone. i tried different RVT colorformats and compression without solving effect.
does the basecolor in the RVT ignore heightblend layer-input? how is the RVT node able to recognize them? and why doesnt it ignore height-blend for e.g. the normal if this tries to be something clever?
