HELP! errors in rendering complex scene

[notamondayfan]

hi guys

 

please see attached the screen capture of my version of vis. im using vray free. my scene is heavily populated, mainly via trees and leaves (made using Tree Maker 5).

 

i believe the problem lies with the leaves. they are on a seperate layer. when i turn that layer off, the scene renders fine. i have not done anything to the leaves other than change their poly material id to match my multi sub materials.

 

is there a limit to the amount of polys vray can support? my machine is easily capable of large and complex renders.

 

thanks, dean

how many polys are there in the scene? and are the leaves single sided polys?

 

if they are it may help if you set them to force 2 sided and change the secondary rays bias to 0.001 in the global switches rollout of vray if its available in the free version.

poly count is thro the roof. dont actually know the figure as when ever i open the polygon counter my vis crashes.but there are like 500 leaves per branch, and there are loads of branches, and around 30 trees.

 

anyway, this is interesting, i can render the scene with the leaves layer turned off, but i can also render the leaves with all the other layers turned off. the building and the surrounding areas area polygon intensive, as im always keeping them low when ever i can.

 

im going to try deleting some trees, and see if this solves the problem.

 

oh and by the way, i dont have a global switches role out, need to preswade the boss to get vray adv!

i found it ironic reading your thread this morning because I've been fighting the same problem - I was getting the same error when I had all the objects in my scene turned on. I'm working on a garden scence with tons of vegetation, and all the foliage is shooting the polygon count through the roof. (Onyx trees are great but they just put a bullet right through your foot)

 

Anyhoo.... I was doing the same thing turning objects on and off in the scene and what I found is that ONE of the pine trees was bad. I deleted it and re-instanced it from another tree.... and all was happy again in vray land.

 

It's a pain to search through all the objects to find the bad culprate.... but it worked for me.

ummm i dont think thats my problem here, because every model will render, but not at the same time. anyway, i have rearanged my layers, so i dont need all the trees showing at the same time, and this seems to have solved it for now. jus annoyed that i cant render 30 trees in the same view.

If your trees are editable geometry, you should convert them to vray proxies, by selecting it, open maxscript listener, and type dovraymeshexport();. A window will popup, check automatically replace the object with the proxy. The tree should be one mesh with all it's leaves. This way you can render very high polycount scenes, proxy allowing less memory consumption.

 

good luck.
