Bonjour

This is a part of a scene i have realised this week .Like you see at the left the Reality -Luxrender seems to render a part of the dress as it was transparent (reduced jpg here ) .Look at the right the same scene rendered by Poser standard render settings

No Ibl or Gi lights  here just standard lights Not Reality light also

Someone has explication for this?

 

Thanks

Hi.

Have you checked the alpha channel setting for that material?

I mean in the Reality material editor.

Looks like it simply didn't pick up the transmap on that piece of the dress.

Thanks

Your are right

I disconnect the alpha (wich works in Poser rendering) from the transparency settings and it seems ok now in Luxrender (still rendering)

You don't need to disconnect or change the Poser materials, just edit the alpha channel in Reality and you will be able to rende rin both situations.

Cheers.

ok 

but i don't really know what you mean  by edit

I see the picture i must edit (white on black backgound) but what i must do on it ? Inverse it ?

In the Reality Material Editor you have the list of materials. You click on the material for the dress and then click on the "Alpha Channel" tab. In there there should be a texture for the transparency map and a value for its strength. Is that value at 1.0?

Also, are you using the latest build, which is 3.0.1.193. If not please update and try again.

Hope this helps.

The way Luxrender works is very different from Firefly and a couple of the differences is that Luxrender gives you a full picture almost form the start but it is noisy.  Also a render in Luxrender never finishes, unless you set limits, it is finished when you like the result and and stop the render.  The longer the render the less noisy it will become, darker scenes tend to take more time to clean up the noise.  

If most of the scene is good but you have a particlar area that is noisy, such as a shadow area you can use the 'refine brush tool' to have Luxrender concentrate on that area a little more.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
