Zakkorn Posted December 7, 2015 Report Share Posted December 7, 2015 I did a test animation with a metamesh trunk and cylindrical roots. The roots had object orientation in the after mesh tab The trunk had Wind animation in the After mesh tab. In the first test I used the stiffness graphics chart to put a lot of stiffness at the first 25% so the roots remained still. But in another tree I made, while tried to do the same things the roots change place every frame. But this time they are not moving because the tree is moving in the wind, but its like they change position every frame (like retopologizing themselves) Whatever stiffness I put, they still move. They only way to make them stop is if I turn off the Wind Modifier in the Trunk After Mesh. It looks more like a bug. Quote Link to comment Share on other sites More sharing options...
Eduard Posted December 8, 2015 Report Share Posted December 8, 2015 To help you, I need to see your model. Please send me your scene file. Thanks! Quote Link to comment Share on other sites More sharing options...
Zakkorn Posted December 8, 2015 Author Report Share Posted December 8, 2015 I have sent you a link with the file as a personal message. Regards Zack Quote Link to comment Share on other sites More sharing options...
Eduard Posted December 8, 2015 Report Share Posted December 8, 2015 Thanks for the file! I think it's better to move the object orientation modifier for the Roots from the After Mesh Modifiers into the Direction Modifiers. As a result, the object orientation modifier will not be calculated for each frame. Leave only Wind modifiers in the After Mesh tab.

Zakkorn Posted December 8, 2015 Author Report Share Posted December 8, 2015 Ok understandable But in my 1st test (as I said I did another test 1st) I had the roots as an after mesh again, but it didn't cause that issue. The roots remained still. I had to put the object reaction as an after mesh modifier, because if I had it in the Direction Modifiers the roots changed shape each time I changed something in the branches. And my question after your solution is... Why the roots have to change shape (or move a little) if the object reaction is in the After Mesh tab? They should keep their position at all the frames. As the wind begins to move the trunk at above 50%. So they have to remain still. Is this a bug or limitation of the plugin? Regards Quote Link to comment Share on other sites More sharing options...
Eduard Posted December 9, 2015 Report Share Posted December 9, 2015 Why the roots have to change shape (or move a little) if the object reaction is in the After Mesh tab? Because the roots grow on the trunk which is slightly moved by the wind... I had to put the object reaction as an after mesh modifier, because if I had it in the Direction Modifiers the roots changed shape each time I changed something in the branches. If the roots are somehow dependent on the branches, perhaps just they grow after branches, then if you change something on the branches, it changes the seed for the roots. But this should not occur if you set up everything correctly. In a pinch, you can bake direction of the roots in the Object reaction settings, it will keep the positions of the roots unchanged.

Zakkorn Posted December 9, 2015 Author Report Share Posted December 9, 2015 Because the roots grow on the trunk which is slightly moved by the wind... OK but as I said, I made with the graph the Flexibility and the Stiffness to begin after 50% on the object length, thus leaving the lower part of the trunk (where the roots grow) unmovable.

Eduard Posted December 9, 2015 Report Share Posted December 9, 2015 OK but as I said, I made with the graph the Flexibility and the Stiffness to begin after 50% on the object length, thus leaving the lower part of the trunk (where the roots grow) unmovable. It seems there is still a very small movement, and yes you're right, with the Flexibility is a small bug. There was a protection from zero, but the value maybe equal to 0. So the bug has been fixed, and later we'll upload the update on the server. Thanks! Quote Link to comment Share on other sites More sharing options...
