The very strong directional light of the background image isn't continuing into the kitchen space.

Did you try add a Sun light pointing in the same genral direction. You could slow dial up the power so it places nice with the internal light setup you have.

Sometime HDRs + Directional can be used together to hack nicer shadows. But re-rendering is needed, which is a painful pill to swallow.

Is this Rayscaper or Twilight?

[Mike Amos]

Ta Rich, this is Rayscaper. Soft lighting is something I cannot find, nor understand the 'fog' I see here. Not talking about dof.

Twilight has a decent ability to create a 'plane' and assign hdri to for direction of lighting.

This hdri is a favoiurite of mine with the sun rays etc.

I have added a directional (Rayscaper) light and set to sunlight which IIRC is 6800k. Aimed into the centre of the view.

Trying a Hotrod which I have rendered before in Twilight V2. Initially opening Rayscaper led to failed renders. Just va simple report, 'Failed'.

Being a Hotrod, there will be flames. The PNG is on a seperate 'face copied from the model and painted as a component. Twilight see's the transparency fine but Rayscaper does not, when it does render.

[Rich O Brien]

Spicy. Interesting that Rayscaper fails. Is this model very heavy in terms of file size?

[Mike Amos]

@Rich-O-Brien

Not that big, nor the texture.

@Mike-Amos do you mind sending me the model?

[Mike Amos]

@pixelcruncher

I have sent an email with a link.

Movement?

Twilight.

Rayscaper.

Something wonky, the 0/0 samples/px doesn't look good. It seems like it never started rendering. What happens if you switch to CPU rendering as a test?

• Menu > File > Settings...
• Tick off the "Use GPU Rendering"

[Mike Amos]

I have already ticked 'use gpu rendering' a while ago when the system was changed.

Hey Mike,

I have already ticked 'use gpu rendering' a while ago when the system was changed.

I just wanted to check if the model renders correctly with the CPU and try to isolate the problem to GPU rendering.

It does render for me using GPU rendering; the model is surprisingly polygon-heavy. I do see the same problem with the flames texture and the alpha channel:

I guess you are using the same flames texture in Twilight Render. I'm surprised it gives such a nice result because this flame texture doesn't have a clean alpha channel. There's a pattern in the alpha channel:

Does Twilight Render have a way to display thumbnails for textures? I'm intrigued at how it can render this so cleanly.

Cheers,
Thomas
