leaves on and off

[Drendir]

We noticed leaves blinking in and out of existence on trees we bought

 

We tried fixing them in the Grow-FX paramaters but can't see any problems to cause this to happen.

 

Wind is in after-mesh modifiers

1.9.9 SP9

all branches and leaves have been placed on 99% pos for the PathPosDistr modifier in Distributors (it brakes the width of the branch when using "Radius < Parent Radius" in mesh modifier, when placed on 100%... - also frustrating)

Hi Drendir,

 

Can you send me this tree?
I need to see all parameters in order to investigate the problem.

 

Thanks!

Can't send it, it's a bought model. I don't think we can just send models over like that, Maxtree wouldn't like it.

 

We'll figure it out on our own. But thanks for the feedback. I found similar threads where you ask for the model, they send it, would be nice if you actually explain in the thread at hand, what the problem was so we can try it for ourselves.

It could be that the leaves are flipping rather than disappearing. You might check to see if all of your paths contain a "vector orientation direction modifier". If one of the paths does not, It could cause sudden flipping. For this tree it looks like all layers should have a vector orientation direction modifier in the "y" direction at 100 Percent. This sets the up and down direction for the path, so it is pretty important. Not adding this to each path can give you unexpected results.  

 

Random and noise modifiers can also cause flipping and mesh breakage. If you have any of these in your tree try turning them off and seeing if that fixes it. Those modifiers should be at the bottom of the modifier stack so that you don't get unexpected results when modifier commands compound.

 

For the mesh disappearing  when < parent, you could try setting a minimum diameter. I think it overrides the "<parent" option, but I could be wrong. Real branches never have a 0 diameter, so I always set this at something like 1/16". This option is toward the top of the mesh panel. 

 

Hope it helps!

Random and noise modifiers can also cause flipping and mesh breakage. // That was it for the leafs thank you

 

For the mesh disappearing  when < parent, you could try setting a minimum diameter.  // The branch mesh isn't disappearing, but the width of the branch was its original size given in directional modifiers and didn't respect the "< parent" option, because it was at 100% in "PathPosDistr". Putting it to 99% fixed it, might have something to do with the "0" size you were mentioning.

 

Thanks for the feedback, the leaves are fixed
