<aside> 💡 Welcome to YMA Painterly! This is a general overview of how to use YMA Painterly to your advantage along with some details for all materials to work with your models.

YMA Color Node System

Because each material can have many different nodes and connections, to simplify things we have added notes along with what we call the YMA Color Node System. All nodes are color coded and organized/grouped together for ease of use/understanding.

• GREEN = Transform Nodes Edit the Master Transforms to change all scale settings in a material at once. Or choose the individual scale/rotation/offset nodes to change each component (texture scale, noise scale, dirt scale, etc). (Sometimes very large or very small numbers are needed, due to your 3D model and scene.)
• PURPLE = Color Nodes Edit these to control color and specular color in the material.
• BLUE = Bump Nodes Edit to alter painterly normals effects. Set to 5 by Default. Anything above 0 will alter how light hits the surface, looking more like painterly normals! Recommend Max value 5
• Orange = Compositing Nodes Optional to edit compositing layers and how all the colors and effects combine together. Also in this area would be how to combine in your own textures. MIX is the the only node recommend to edit.
• GREY = Building Block Nodes These are all various kinds of nodes recommended do not edit.

Lighting

Higher intensity on lights are recommended. Try to use color in your lights as well, almost as if painting with lights. Don’t be afraid to increase saturation in your HDRI as well!!

In your Camera Imager or in Compositing play with higher saturation because higher saturation will feel more like paint!

HDRI (Default)

HDRI (Saturated)

1. Open Node Editor
2. Add Color Correct Nodes
3. Add UVW Node at the end

UVs

ALL 3D models should have some basic UVs. Materials will look incorrect or stretched without proper UVs. Textures will be warped and/or not “stick” to deforming geometry.

For more in-depth explanation about Octane + UVs/Projection please read Scott Benson’s Octane Intro to UVs and Projection.
