Hello guys,
I have a problem with render results,I want this wood texture to be in high quality and detailed but the render results are very bad.
The wood texture its from Poliigon - 5K,even the render resolution its high (4200x1900) and 100 passes but the results are still bad.



Thank you!

Hmm - looks like either the material or the UVW mapping isn't setup right (looks like the wood is just a single colour rather than the Poliigon texture)...

Does this material look ok if you apply it to some other object, like a sphere?

I fixed the UVW but still the problem its on render settings I guess,when I used vray I increased the subdivs on material settings or on render settings and it incresed the quality,when I zoomed in it didn't look blury but clear.
This is my render settings

Well, in Corona, changing render settings will not change the appearance of materials, and is not required at all. The defaults work just fine.
So if you zoom in, the material is sharp? If you move your camera away, it becomes blurry?
That sounds like filtering. Can you please open the material editor, sample the offending material, select the bitmap which is loaded as diffuse color, and show me the screenshot of that bitmap's settings?

Yes of course,I uploaded aslo the UVW Map settings.What i'm willing to achive its to make the wood texture look more detailed and clear when I zoom in.

If you show the wood map in the viewport, how does it look there (can you take a screengrab of the viewport showing the wood mapped correctly?)

I fixed the mapping,you can see it on the last my last attachment,the problem its the quality of the render on the wood when I zoom in.

Well... Honestly I can't judge anything from your last render. Wouldn't even know it was wood if you didn't tell. No one can see the actual quality of your material from your pictures, and therefore it's quite difficult to tell what's going on and help you fix it.

This could be caused by many things, and as already mentioned it sure looks like the UVW is off. Does the geometry come from CAD, or has it been scaled on object level? This could cause a correct UVW showing wrong result.

I would suggest you use a reflection/glossiness map with nice contrast that will define your highlighted side of the wood construction. It might also be a good idea to pump the bump/displacement on the material to break the flattening.

Lastly, you might want to increase your render resolution and decrease your image filter to find a perfect balance. It would be nice to know what's the noise on the final renders you provide as well as what type of denoising you are using (if any) and at what amount.

Thanks.

What we see in your images - is that even a texture, or just geometry? The vertical lines look like geometry.
Maybe you simply need to increase your render resolution?
I really do not understand this report.
