Hi i've just switched to corona and I'm facing some limitation or it's just me non findg what i am looking for.
Im having an hard time tiling different bitmaps applied in the same material.
simple example concrete with splotches into an object with UV coordinates (important note)
Tipically we would have into one layer the concrete bitmap on top the splotches bitmap with some blending mode, lets say that i want to scale the splotches 3 time smaller compared to the concrete bitmap so i will put this last bitmap into a projector shader set to UVW and set the tiling to 3. everything works great
lets say now that i want to use the same material into and object that doesnt have the UV coordinates so i set the material to cubic projection, unfortunatelly the splotches bitmap inside the projection remain set to uvw and do not work properly.
i think we need a dedicated shader that is able to ''scale'' texture without forcing a projection mode, it could be directly integrated in the corona bitmap shader, kind of like the vray advanced bitmap where you can control the tiling of each bitmap without taking care of the projection.
nb: triplanar is not a solution since it would messed up the concrete projection in the object that has UV coordinates.
