photoworks2 help please!

Hi,

I'm trying to do a quick rendering of some clear acrylic parts that are fastened to an aluminum frame. When I render it areas where there are several layers of acrylic (more than 2) the aluminum extrusion renders a dark gray. I've tried turning up the depth settings to no avail. I've been using a 'translucent plastic' with the transparency turned up to simulate acrylic. It's like the ray tracer can only see through x number of clear faces before it gives up....

Any ideas would be gratefully received!

Zander,

I've had a similar problem.

Try these things:

Go to the PW2 Materials editor where you've defined the acrylic parts and ake sure the COLOUR of the material is set to dark grey. Sometimes everything will be transparent but the colour is set to a mid grey and it makes it seem like it's not as see-through as it should be.... set it to white or near-white and that should help.

Also, go to the scene editor and go to the shadows tab... make sure "transparent shadows" is selected. This takes a LOT of processor power but is really the only way to get realistic renderings of things inside glass cases.

These in tandem should allow you to produce a decent image.... hope this helps!

George.

Zander,

Unless they've changed things lately, you are correct in that the raytracer can only see through x number of clear faces before it gives up. It would be too computationally intensive to trace every bounce of every ray as it reflects and refracts into infinity. To avoid crunching numbers forever, raytracers set a cap on the max number of reflections or refractions. To adjust this in PW2 you should be able to go to the PhotoWorks, Options dialog and set the max number of reflections and refractions a ray takes before it dies. (It's been a while since I've been in PW2, so you may have to look around a bit in the PhotoWorks, Options dialog).

I hope this helps.

Oops.... in my first post that should have read that the colour is NOT set to dark grey...... but I'm sure you probably figured that one for yourself.

I'd be pleased to know what outcome you managed to come up with :)

Happy hunting :)

This tells us quite a bit about how badly SW screwed up on PW2, when the PW_Guru himself hasn't been using it for quite a while!
