View Full Version : LW 9 Crash after Subdividing model

03-13-2007, 12:56 AM
LW 9 WinXP Pro on P4 2.66 Ghz with ATI Radeon XPRESS 200 2Gb RAM

This is my first post, I’m totally new to lightwave and I can’t seem to figure out why this happens.

If I subdivide and smooth the texture of a sphere in modeler 9 and save it, LW9 crashes if that object loaded into the scene.

All other LW9 functions work fine so far.

Any suggestions would be great.

How many times have you sub-divided the sphere?

- If you go too hard, as in subdivide the object too many times you'll end up with way too much geometry for the scene to work.

-you can assign values to the sphere first -up in modeler by selecting the make sphere tool then hit "n" for it's numeric settings.

- Check the p/p ststs in Modeler (hit "w") before sending the model to Layout. You will probably start to freak your system out in Layout around the 50-90 000 polygon mark. Don't know really, I use macs.

Sounds like you have made a regular nuetron star though?

Thanks for responding...

I hit subdivide once.

My sphere has a 4m diameter.

With surface smoothing on:

- I have found that in numeric > globe, I can go as high as 24 sides and 24 segments
- I have found that in numeric >Tessellation, I can go as high as 5 segments
- Any value higher then theses and layout crashes…

With surface smoothing off:

- I have found that in numeric > globe, I can go at least as high as 192 sides and 192 segments
- I have found that in numeric >Tessellation, I can go at least as high as 48 segments
- Theses values cause huge memory drain though…

With surface smoothing on, I do not get the memory drain but the edges of the sphere are more erratic then I desire.

I hate to give up but, maybe I just have to live with it if no one has seen a patch for this.

... no problem! Don't give up!

-If you can go 192 sides with smoothing off, which is **** you'll most likely never need, it suggests there is some problem with the shading rather than the geometry.

- I don't know 9.0 but it may be that you have added some motherlode texture accidentally which when smoothed, goes to overload?

-How about when you sub-patch it?

-Try the same with a box?

-Keep at it!!

Well that took awhile for me to figure out.

I think my computer could be the poster child for the bare minimum requirements for LW 9.

After upgrading to a Pentium D 945 3.4 gig CPU and Installing a PCI express video card, now I can smooth my models.

Thanks for the encouragement…
