RBD - Rigid Body Dynamics. Convexs - they have to be manifold objects. Concaves - cannot be a non-manifold objects. Vorono, RBD material fracture, RBD configure, RBD bullet solver. Voxels - volume pixels. Box - transform - RBD material fracture - RBD configure - RBD bullet silver. Select the wing, group create, blast the tip/edge, polyfill, normal/compute normals. Then, do RBD material fracture. RBD exploaded view to have a look at the different pieces. Merge normal wing with broken edge then normalise it. Have to tweak the clusters using another engine like RBD called vellum. Most uses of cloth. It acts the same way as RBD. Box, vellum constraints - vellum solver (pay attention to substeps) - grid - add mountain noise - vellum process. Try to create a mountain with snow on top. Like clumps on top using vellum process. Click brain icon in bottom right corner to stop processing the current simulation. Vellum constrainst gains - click grains - select particle size and packing density. Vellum solver - select substeps, click ground position to get ground. Particle attribute look up. Add a colour or use a map. CD which we are adding to grains locks onto frame and projects the UV and onto the grains. Point VOP for each point we are bringing second input. Take each of grains and the UVs for the second input. Then, get each point and export it and attribute it to the map and export as CD. This causes the grains to shrink but now it has a snow texture. Approach will always be the same and make sure you are always doing it in low res.
