domsewell posted a topic in Tools (HDA's etc.)Hi all, I have set up a tool that takes an input mesh and performs an operation that writes new vertex color to this mesh. I am looking for a way for the HDA asset inside unreal to take the input mesh and overwrite the vertex colors of that specific instance in the world is this an achievable effect? Thanks all, Dom
Hi wizards! Im struggling with a problem, that when i thought about it i thought it was really easy to solve, but nope! haha So, we did a character inhouse, sent to a guy (rigger/animator), he did his own rig, animated the character and sent us back an alembic ready to render. The issue: the animation is fine but there were a minor changes on the model. This guy went on holidays for a month, so we don't have his rig setup. Now, we took the model in the first frame, we moved some points in zbrush to match the feedback and took it back to houdini to check that all the point number and polycount are the same. The question: - Is there a way to take this new model (same point number, same polycount), transfer somehow the new point position and apply the animation from the wrong model to it? I made a dummie scene of situation, i would really appreciate if someone can help me with this! I will keep working on a solution but maybe u already faced this problem before! Thanks guys! alembic-replace.zip
Juraj posted a topic in Lighting & RenderingHello, Mantra during rendering is always converting all non-rat textures into rat and then discarding them after the render is finished. So I am considering batch-converting all of them to rat using the iconvert tool while keeping their original name and replacing only file extension. Batch conversion of textures is not a problem, but I am curious about re-linking them in shader networks. Arnold has an elegant solution for that - it checks if there is a .tx version of a texture and if so, it will use it and save some time. It also allows to do one-time conversion during the first use of a texture and then it will keep .tx version around inside the texture folder. So I am humbly hoping that there is somewhere hidden feature for this behavior also in Mantra. Any experience with that? Otherwise I can just scan all shading nodes in Houdini with python and replace texture file extensions for rat. Thanks, Juraj
