I need an advice

I’m not sure what you mean by ‘random shades’. I need to see a screen dump. Use Blender main menu > Window > save screen shot.

If you have double faces on the same spot, which can happen easily. Then they will ‘fight’ for visibility and showing strange artifacts. In edit mode select all vertices and try ‘merge by distance’(right mouse click).
If you render in Eevee also things like ‘light bleed’ can happen.
If you render in Cycles it can happen that cycles needs more vertices (faces) to solve the smoothing of objects.

Maybe this will help?

here for example my old model, in my last attempt to create the rifle I also got random horizontal shades on the stock, although I had small amout of faces that time

FedPete · January 30, 2022, 5:25pm

in edit mode select ALL faces.
Then press shift n to normalize the face normals …

FedPete · January 30, 2022, 5:27pm

Also (I can’t see) check inner mesh on that spot. It can happen you’ve an inner face inside that spot.
Use X-Ray mode to see if it is there. Or still check for vertex doeubles.

Oh, it really had a face inside lol, idk how it appeared but now shades are gone, thanks

Hey, It’s me again with another question :)) So I was doing another gun model and got some weird situation with bevels and the shadows they caused. Is it because of bad topology?

Not sure how can I make it properly, shift n doesn’t help…

Hopefully someone will correct me if I’m wrong, but I’m guessing it’s because of your n-gon. If you used the knife tool and made edges like this, it might fix it:

Veeran · January 31, 2022, 10:13pm

Sadly no, it doesn’t fix it

NP5 · January 31, 2022, 11:46pm

Yes topology.
Right idea Zach.

Remove red edges, add blue.

Veeran · February 1, 2022, 12:41am

It got better, but still there are weird shadows

A matter of how much more geometry you want to have for the area it is in. You could take the side two faces that join onto the bad shaped quad through it and up the left hand side. You might get away with selecting those new quads and making them shade flat. Edit; face, shade flat.

put an edge loop… GG (Edge Slide) - Drag to wards the corner that is getting sharp.

FedPete · February 1, 2022, 9:04am

Do you have inner faces?
Have you checked for double (vertices)?

Veeran · February 1, 2022, 4:35pm

No, I don’t have any, noticed only couple of double edges, but deleting them changed nothing

umishrak · February 1, 2022, 5:12pm

can you upload your file somewhere, so that people can look for the possible solutions?

Veeran · February 1, 2022, 5:28pm

here is the blend file, I hope this works

umishrak · February 1, 2022, 5:31pm

You have not applied any modifier? or is it missing on the file I opened?

umishrak · February 1, 2022, 5:34pm

This is an extremally bad geometry. Have a look

A reworking is a better option!

Veeran · February 1, 2022, 5:35pm

on the object that I showed here, no, there are not any modifiers. I have other model in the same file hidden with subdivision modifier but I was just practicing you know xD

Veeran · February 1, 2022, 5:36pm

Yeah, this is another issue that I got from bevel tool, I wanted to make those edge loops down to the bottom, but then saw shadow thing that I was talking about at the bottom, so yeah
