Foil wrap noise spot

[rvscc]

Hi I tried everything.
I have a black noisy spot on my render.
How can i remove this?

Thnx Rob

Decrease the "White point:" of the Shadowmat if this is something you have in mind. Why not skip the Plane.1 at all?

Cheers

Well i need the background for realistic shadow.
Is there something else to try?
I tried with a regular material, but spot is still there.

A shadow of what, the foil or the box? Is the spot or the noise?

 

[rvscc]

Yes i don't want the foil to be floating in the air. It needs a floor.

 

[frank beckmann]

Mmmh - still unsure about the result you want to achieve.
Excluding the plane from seeing by the camera via Render-tag will look like this:

I stay here till we get it sorted.

 

[rvscc]

Thanks but not what i need.
The shadow in my render now is noisy or broken.
I like a natural shadow.

I´d try with Falcon then. Give the foil a tiny bit of a thickness and enlarge the plane to fit camera view and add a white diffuse material to it. studio020 is set to Intensity:4 and that´s how it looks like:

Well that looks brilliant! but i don't have falcon. Will look up.

But still wondering how this could be done with cheetah 6?

 

[frank beckmann]

Uuuh - I didn´t know that. Are you still on Cheetah3d6.xx then?

Darkened area behind glas/transparent objects always have been tricky to master - if that´s possible at all. I remember these kind of threads very well - but there´s no instant bliss switch that can be turned on and everything looks as "wished".
Your scene looks more like a proof of concept than a real job - can we if I´m right proceed with a more "lifelike" scenery then?

Yes i'm testing before i can work on this project. I need to make renders of a series of window films. But the focus is on the film. The scene background will be very basic.

 

[rvscc]

I just replicated a transparency from a default material, edited some trans and reflection. looks ok. It seems to be the plastic preset.

 

[frank beckmann]

Never heard of the term "Window film". Is it kind of transparent paint on glass or something like that?

 

[rvscc]

Yes its a transparent foil for UV protection or heat control.

 

[frank beckmann]

Ok - I transferred the file to Cheetah3dv6.3.3 and it turns out pretty well. Let me hear what you think:
I just shrunk it down for the forum.

Cheers
Frank

 

[rvscc]

Wow thnx!

 

[frank beckmann]

Ok - good luck with your project.

Cheers
Frank

@Frank I use window film on the windows in my office to keep out the summer heat. Works great.
