a_tekautz Posted March 23, 2015 Report Share Posted March 23, 2015 Hello Eduard and others ! There is an issue I run in while animating "Cracks". I am using direction modifiers "Noise_dir" to keep it natural (even if the client maybe will prefer straight lines, then the problem would be gone..). If I don't use variable "strength" parameter, then the animation is just fine, but the branches won't start from the "trunk" immediately but randomly offset. If I use variable "strength" parameter with a rising curve, then all branches start from where they should, but animating the tree-crack this parameter seems to scale to the length of the actual branch - so every crack is changing its shape while growing. The same is true for children branches, the start to jitter as the parent branch changes. This would be no problem for a real (timelapse) growing tree or plant, but in my case a grown crack (inside of a rock for instance) can never change its shape. Is anyone aware of a quick solution? I hope I could be clear enough to describe my problem. I attached a test file with a Trunk and four child branches. Inside of B_01 I disabled the "Strength" graph of the Noise_dir modifier, the others have the graph enabled. You can quickly see the issues an differences. I tried to lower "Step" size continously as there are similar issues when the steps are to large. Thanks! andreas 02_Crack_2D.max Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 23, 2015 Report Share Posted March 23, 2015 Hi Andreas, Please let me know, what is your 3dsMax version? Thanks! Quote Link to comment Share on other sites More sharing options...
a_tekautz Posted March 23, 2015 Author Report Share Posted March 23, 2015 Hi Eduard! Thanks for the quick answer - max 2014 thanks andreas Quote Link to comment Share on other sites More sharing options...
Eduard Posted March 23, 2015 Report Share Posted March 23, 2015 Ok, thanks! I think you need to add an Affect for each path, from Parameter: Length on Noise_dir_01->Strength. See my settings in the attached file: 02_Cracks_03.max Also to reduce the file size, I removed all the hidden objects... Cheers Quote Link to comment Share on other sites More sharing options...
a_tekautz Posted March 23, 2015 Author Report Share Posted March 23, 2015 Thanks Eduard! Sorry for the "bloat", I sent the wrong file - that one before removing hidden stuff I am not sure whether I geht the point, or if you did understand me right. I see the same problem in your file..? Anyway, I will use an older file with reduced noise without gradually "Strength" and deal with noise in the next days. For my preview that has to be finished it will last Thanks a lot for your great support! Cheers andreas Quote Link to comment Share on other sites More sharing options...
