In this new rendering i used a cloud clip from the resource in the forum (Clouds_Stonngae.tgc), i'm quite satisfied with it, but i'm experiencing some artifacts with a model that i created, It has a color map and specular map, but not sure that i appllied corrrrectly in the render node. the model was created with 3dcoat. I also created the bump map, but terragen crash when i applied to it. I will open another topic for this, because i didn't found any advice looking in this forum ( i mean topic regarding the best process to export from 3dcoat to Terragen for the bump map).
