Looking for procedural noise for large scale scenes ? Groundwiz might just do the trick!
AwesomeBump 4.0 is a free and open source program designed to generate normal, height, specular or ambient occlusion, roughness and metallic textures from a single image.
Bakes texture maps: Diffuse, Reflection, Refraction, Reflection Glossiness, Refraction Glossiness, Normal Bump, Fresnel IOR, Opacity, Illumination.
The auto-loader loads bitmaps from a folder into the corresponding layers for bump, diffuse, reflection and displacement, without the need to manually load every single bitmap by hand.
Just select a folder with bitmaps and leave the rest up to Crossmap LE. Crossmap creates more variety among visualization projects easy and fast, for example leaves on trees, grass, gravel, stones, flowers, wood fences and many more.
Whenever you tried to get color variations on objects you were probably encountered with picking different colors from photos and assigning them to materials and objects to get more variation.
COLOR COMBINE combines three different maps into one map where each map represents one color channel (RGB).
