Thanks man , but is there any hip plz ? , im not sure after promote what will be in the Convert process bcuz here i have same issues -
Hi, After some quick advice please. With the mpm solver presets in Houdini 21, I can't quite work out a setup where i bring in a sphere and then use that as a surface in mpmsource and have it tear apart when it hits a collider. All I really end up with is the collider kind of hitting the particles and pretty much pushing through the particles, and particles don't quite rip apart. If anyone has advice for settings or presets (or online tutorials) that would be great. Thanks -
You can add attributes you want to keep during the conversion process, but that does double or triple your memory usage. -
When I create a default poly sphere, the coordinates of point 0 is 0, .5, 0 and point 1 has 0,-.5,0. looks correct to me. N is usually v@N what means it is a vector - more or less. All vectors consist of three float values. The only difference is how they are handled during tranformations. Because you use ch() what usually defaults to float, what you need is a vector attribute chv(). The docs are quite helpful with this. Seems you did not read the docs for the attributeExpression sop node. The expression should look like this: set(self.x,sin(self.x),cos(self.x)), but I recommend to use a wrangle node, I didn't know the attributeExpression node exists until now. -
