whats that? never saw that before: on my diyplay option toolbar is a big red dot with the message: ERROR: (material/GL32/beauty_primvertnorm_lit.prog) GLSL Shader failed to compile. and nothing is displayed in the scene view. Already reinstalled HOU 18.5.496 but nothing... Any Ideas? And of course I have to finish a job today.... :-( edit: installed the newest nvidia driver (496.13) before and I think thats the problem. reinstalled an older version (471.68) of the driver and it work again... wired... Despite this would be a hint great...

Phantastic, thank you. I didnt recognized the null way from the switch. Was deep in the loop involved that I missed everything outside... lol And thank you for the examples.

I found this file wich is in the atachement. How does this work? I mean where are the function for deleting the spheres wich intersect each other? Is it the job from the intersection anlysis? But if so, where is the connected Output from the intersection analysis? I really dont understand the logic behind this scene. Who could give me a hint / explanation please? untitled.hip

Haha, now I got it. Thank you to you both. F.. Typos...

äh, I dont understand exactly what you mean...? I declared the m3 as a matrix3 the matrix 4 is needed for packed objects and/ or v and/or w, isnt it?

I try to copy the intrinsic data (matrix3) from a DOP animated to an static object. Unfortunately the rotation vector is somehow funky. Have a look at the hip please: Credits: Tutorial by Alessandro Nardini on you tube: https://www.youtube.com/watch?v=s9DjkDt-6Js Smart_activation_4.hip

whats the beat way to have dif. HOU versions AND dif. home directories? Is there a way to add something to the link or ow do you handle that? Thanks on advance. Stay healthy and keep going...

ok, thanks anyway. I already solved the problem by myself - foolishness... ;-) So its solved.

doing a tutorial, the Railsystem. In the moment I stuck with a lerp function in a wrangle. It dont takes the, in this case spline, whole geo, just a part of it. Please have a look onto the hip to show my problem. I dont know whats wrong with it, I dont find it. Could you help me please? Railsystem_Chapter_2.1.hip

want to setup a grain sim but my grains are not shaded correctly in the viewport: Dont find a solution to display the grain correctly. Have anyone some advice please? Never had that before...

I'm sure, the question of how to print the network view, isnt really new. But I am not a python crack so my possibilities are limited... Does anyone know how to handle the printing of the newtwork view? Better would be a tool for displaying and printing also the whole dependencies together with the nodes.... Thanks for any suggestions

the first problem in my setup is that the bendend object tend to go back to its initial state. I grabbed the initial constraint, copy the primintrinsic "packedfulltransform" - the transfomationmatrix from the packed pieces onto it. In my sugggestion the sopsolver should send it to the rbd solver for the next step. So it should bend more and more. Unfortunately it goes back into its original position. Like there wouldnt be a sosolver and/or the constraints are totally wired. Why the constraints are bending back to its original position instead to bend more and more. If the last state of the constraints is the maximium bend state and the new origin constraints are already bent (this one I changed with the copied transforms from the bended geo), from where the rbd solver get its information to use other constraint states instead of the new initial state? metal_bending_02.1.hip

a little bit tricky to explain my point of needed help: building a system for bending metal. I'm not using softconstraints rather hard constraints. In the constraintnetwork sopsolver I pick the original constraints, copy the 4matrix from the geo and want assign the new constraint network back to the bulletsolver. First problem: How to solve the usage of the new constraints, seems like the rbddolver dont use them. I think there is a big mistake in my setup. At an other state I already posted in SFX Forums and get a plausible help from "Miccetro" (https://www.sidefx.com/forum/topic/79064/). But as I wrote I want to go with hardconstraints and change the constraints. So could anyone have a look at my hip and examine it for eventually furher help? ^^ Keep healthy. metal_bending_01.hip

in a relative simple setup for metalbending my DOP make problems. Starting with not desired movement of the object. Would you mind to have a look to the hip, please, and give me some tips (advice)? I just overlooked something I think... Dont find it quite now. metal_bending.hip

if I create an empty volume sop with i.e. dimensions 5*5*5, nothing is visible, nor the bounding box. In a tutorial wich I'm studying quiet now, there is at least a bounding box. Newest graphicdriver; Houdini ver 18.5.462 Any idea? volume_sop.hip
