I have a (simple) scene in Layout (a table, four glasses and a glass (tea-)pot). A single spotlight illuminates the scene.

As long as I render with CAUSTICS OFF, I get the resulting picture in under 2 seconds. If I turn CAUSTICS ON, the rendering will abort while "Tracing caustics from light (56%)".

Any idea what could be causing this ?

Regards,
Andreas Cocq

When you say abort do you mean crash or just stop?

If it stops watch the render status and see if it says anything like 'Not enough memory' it will only appear for a short time if an error occurs so unless you're watching you could miss it and wonder what's going on!

Just a quick Question:
Have you got your 'Alert Level' in LightWave set to 'Expert'? (its under general options (press O))

If you do, switch it down to 'Beginner' - I leave mine at Beginner level now, since it forces you to acknowledge error dialogs (so you never miss them - Its easy to miss out something important in Expert mode!)

Hi guys,

thanks for your suggestions ...

As it turns out, I was using the SimbiontLWShader (DarkTree) for one of the surfaces and that is what caused to problem. Once I removed the LW Shader everything worked like a charm !

Cheers,
Andreas

Andreas, Ive the same problem here with a house and windows and stuff, well caustics crashes LW all the time, even though I removed the Simbiont..... It seams like caustics are still buggy and picky to manage.... and I just cant start to look all over for what could affect blah blah blah... so no caustics.... hey NT can you fix the caustics, there are sooo many complaints about it I could fing here in this forum doing a key search... incredible....!

Cheers
Hervé
