Hello everyone, I am new to Model Texturing using 3D Coat. I have created a rough concrete material using 3DCoat and I like how it previews in the Smart Material Preview panel. However, when I fill the whole model with the material, the material fills but in a big scale and looses the fine details as shown in the Smart Material Preview. When I try to reduce the scale of the material after filling, it comes nothing close to the Smart material preview. I have attached a Screen shot to elaborate this. What could I be doing wrong? Thanks in advance!
