Copernicus COPs workflows in Houdini
Copernicus COPs workflows
creating materials with textures from COP network
build a preview material in COPs add null nodes for basecolor, height, etc. go to /mat context add karma material builder node and dive inside add mtlx image node: basecolor signature: color (feed into mtlxstandardsurface) add mtlx image node: metallness signature: float (feed into mtlxstandardsurface) add mtlx image node: specular signature: float (feed into mtlxstandardsurface) add mtlx image node: normal signature: color (feed into mtlxstandardsurface) doesnt work.... in karma material builder!! ev. write out textures and try again add mtlx image node: height signature: float (feed into mtlx displacement) mtlxdisplacement: scale: 0.03
testing textures in /geo context
add some nodes in COP network and add a NULL node at the end select NULL node -> copy c (to copy path) go to /geo context (add some geo) add uv quickshade node texture map: op:/img/copnet1/texture_OUT (press copy v in the texture map field, add op:)
changing image size/resolution
add size ref node in front resolution: set something
circular pattern
add ramp node signature: RGB type: concentric number of circles: 10 outside range: mirror select a preset for a color gradient
masking nodes
add 2 constant nodes one white one black (RGBA and transparent) add ramp node add blend node feed constant nodes into fg bg and ramp into mask
tinting with a color
add bright node shift: 0.5 tint shift: set some color
substract or add two shapes
(illustrator pathfinder) add sdf shape node shape class: compound compound shapes: versica add another sdf shape node shape class: compound compound shapes: fishscale add sdf blend node mode: union add sdf adjust node
colorful noises with ramps
add bubble noise node add remap node output min: -1 add ramp node number of cycles: 2 select a preset gradient (wheel icon)
tile patterns
add sdf shape node add sdf to mono node add tile pattern node plug sdftomono into stamp0 pattern type: windmill add segment by connectivity node (to color the pieces)
