Description

BakeTextureFromCollection (v1)

Bake a texture from a geometry collection
Output to a 4 channels Image object ( RGBA )

Input(s) : Collection [Intrinsic] - Target Collection FaceSelection - selection of faces to bake : if not connected, all faces will be used Resolution - resolution of the image to bake GutterSize - Approximate space to leave between UV islands, measured in texels UVChannel - Index of the added UV channel MaxDistance - Max distance to search for the outer mesh surface OcclusionRays - Number of occlusion rays OcclusionBlurRadius - Pixel Radius of Gaussian Blur Kernel applied to AO map (0 will apply no blur) CurvatureBlurRadius - Pixel Radius of Gaussian Blur Kernel applied to Curvature map (0 will apply no blur) VoxelResolution - Voxel resolution of smoothed shape representation SmoothingIterations - Amount of smoothing iterations to apply before computing curvature ThicknessFactor - Distance to search for correspondence between fractured shape and smoothed shape, as factor of voxel size MaxCurvature - Curvatures in the range [-MaxCurvature, MaxCurvature] will be mapped from [0,1]. Values outside that range will be clamped

Output(s): Collection [Passthrough] - Target Collection Image - Output image with the bake attributes UVChannel [Passthrough] - Index of the added UV channel
