@csehz thank u my man it s good to be here !

@csehz I think if you have a photorealistic texture which has to look the same as it would be photographed, like wooden floor planks, it’s better to uv unwrap to make sure it sits perfectly right on the surface. Also if you want to paint your own textures uv unwrapping would be the way to go. 

But for something like grunge/scratches/dents/etc you can use coordinates and box project, since you want variety with that. It’s harder to place it exactly where you want but you can make sort of a mask with something like a noise texture. 

In Cycles you can also use the pointiness value of the geometry node or the AO node to mask out edges / crevices, but in eevee that doesn’t work (yet). I’m assuming you’re using eevee since you also love it like me! 😀

For my scene I’m working on I only unwrapped the floor and the wall, since that’s just a plane. I’m not good with unwrapping yet, so for the rest I use texture coordinates and box project.

[Grady Pruitt]

@csehz I’d agree with what @smurfmier1985 said. When it matters that a texture appear precisely in a spot, UV is best. For example, the clothes that I put the stripes on, for them to look correct, you have to use UV coordinates or they don’t look right, particularly around where you would naturally see seams anyway. I have used stripes in Generated or Object texture coordinates, but in those cases, I’m often doing something more abstract and the placement and look is a bit different and can, in some cases, be harder to control the overall look. that’s why for things like grunge, either works just fine.

[Grady Pruitt]

@arev If you could share a screenshot of your scene and/or a file, that might be helpful to help solve the problem.

You might take a look, in the mean time, on the color management tab and see if you have curves turned on and make sure that the red channel hasn’t been accidentally turned up.

[Morten Fjellheim]

@gradyp I dont have curves on so i have no clue whats causing it. I did find that filmic wasnt on, but turning it on diodnt help much. I am attempting another render with a slight change to the lamp setup, if it doesnt imporve i will leave ut for another time.

[Zsolt Cseh]

@smurfmier1985 , @gradyp thanks a lot, briefly so texture coordinates can be used when the image is tileable and no need for specific precision, while the UVs are better in that.

I’m assuming you’re using eevee since you also love it like me! 😀

Miranda yes absolutely! 🙂 Eevee is so much fun that all the shading and lighting changes immediately can be seen, anyway it is my only chance also to meet the deadline, since with Cycles it would be much harder to reach to the point of the final render on my oldie laptop. Okay maybe the final render would be anyway a little bit better still with Cycles, but the Eevee is already ideal for the travel till that. Or how to say 😀

Oops the dealine, 23:59 is here and did not post anything yet for Week3.. 😀

[smurfmier1985]

@csehz Eevee rocks! 😬

You can also use non tilable textures with the texture coordinates. The ‘box project’ function on the image texture node projects it from many different angles instead of one angle, to make it look more random. Works great for grunge and scratches etc. You can up the blend value of the image texture node to make it less noticeable that it isn’t tiled, that gets rid of the seams.

@csehz 

pro and contras regarding using texture coordinates instead of UVs

Just try to unwrap dyntopo sculpt 😀

[Zsolt Cseh]

@nekronavt yes I know 🙂 

Is it also 01:35 AM your time? 😀

[Pavel Mazanik]

@csehz 2:37 😀  

[John Fluet]

@theluthier  Sorry to make you struggle with my username each week.  You can pronounce it “Cah-thool-oo-san”.  Inspired by Lovecraft’s Call of Cthulhu and chosen very late one night when I had to pick a username for my deviant art account.  

Loving the class so far.  Learning tons and it has me in the software doing specific things and stretching my blender muscles.

[Morten Fjellheim]

@theluthier Can we use eevee for the week 4 homework?

[smurfmier1985]

@arev Yes you can, I’m using it for all my homework. Only week 2 had a specific render engine, the rest of the weeks you are free to  choose

[Kent Trammell]

@cthulusan heh no worries – there are far worst usernames to pronounce lol. I’ll try to remember the correct pronunciation 🙇🏻‍♂️

[Kent Trammell]

@arev Yes Eevee and Cycles are both valid options for the homework – your choice 🙂
