Was watching this tutorial on Trim Sheets have heard about them but never really got the concept till I watch this tutorial he also uses a recently devolped add-on for baking maps that time wise was easier than the usual manner of map baking it is called GrabDoc map baking the tutorial creator explains its use at about 25:30 into the video if you do not want to watch the how tutorial

WTF are... Trim Sheets??

Good tutorial. One thing I didn't care for, and I see it being done in a lot on tutorials for Blender, is that he never changed the color space of the normal map texture node to Non-Color. Using sRGB color space with a normal map in Blender will provide incorrect normals. I know it sounds like you should be using RGB color information with normal maps because they are made up of color vector information to begin with, but that is not the case.

The Normal Map node itself converts the data information contained in the normal maps to the corrected vectors anyway, so you are basically doubling up on the vector data information if you use sRBG color space in the texture node. Always use non-color data for every single texture node that isn't the Base Color or the SSS Color. Everything else in the Principled Shader is a data node only, so use non-color.

The addons are great though. Especially the baking addon. It just kills me when I see people who make tutorials use the sRGB color space for normal textures. That will always screw up the normals on the model.

Thanks for sharing that LuxXeon I had not noticed that even thou by habit I always change the normal map texture to non color by habit after past errors in previous use of normal maps then once it became habit I do not think about just do it because that is what should be done but it si a good thing to point out maybe a tutorial on how to set up normal maps by be a good idea when plugging them into the Principled Shader

I didn't watch the whole video, but that definitely looks interesting. I'll have to check it out again when I get around to updating my Blender, since I'm still using 2.79.

Yea, I noticed that about the normal maps too! I appreciate people making tutorials but that is something everyone needs to know. It's in the blender docs that if you use a normal map node, the textures need to be non color.

Miss B, why still using 2.79? Blender has changed so much since then you'll basically need to relearn a bunch of stuff if you decide to update. Latest versions are even way different than the original 2.8 release.

This guy does a decent job at describing how to use the Normal map and Bump Map nodes with Principled Shader in Blender 2.8x and higher.

BTW, I think that the baking addon featured in your original post is fantastic! There is a paid addon called Simple Bake which does the same thing except it has a few more features, but that one you showed is excellent! Perfect for baking procedural textures into PBR maps with minimal setup or hassle.

Because I've been using Blender since version 2.4x, and getting used to a new GUI with 2.52 was more than enough, though back then it was absolutely needed.

I know they've redone the GUI starting with 2.8.x, and now 2.9.x, so that n00bs who were having issues with the 2.79 GUI could use Blender with an easier GUI to work with. I'm very used to/comfortable with version 2.79. One of these days I'll install the newest version and play with it . . . just not yet.

I still fall back to 2.79 since most of the models I have built were made from 2.62 thru 2.79 but finall saw something that I seemed to have missed when trying to open files from 2.79 into 2.8 or 2.9 and that is if you un check load UI will make a word of difference in Blender 2.9 to get to load UI option click on the cog wheel and then uncheck load UI see screen shot below I actually didn't that you could do that lol

@Lux thanks for pointing that important fact about normal maps colorspace. This is especially critical for human skin in my Iclone/CC3 based Character animation pipeline.

I use the Reallusion supplied "micro normals" from their "Digital human Shader" system ported over to Blender via FBX from CC3.

If I Dont switch to non-color my characters skin turns flat Black completely wrong & useless.?

Re: uprading past 2.79 For years I made honest attempts to become a Blender user in the Pre 2.8+ era,even the so called "Blender for artists" versions and was always sent running back to C4D.?

After finishing my six year long animated feature length film project, I was so desperate to Dump my aged C4D(R11.5 studio) and Move away from the Mac OS to windows, that I was in the early stages of migrating to an old seat of the ( likely Doomed) Lightwave3D 2015 I had acquired for Win 10 on the cheap.

Then came Blender 2.8 that ,for once, actually lived up to the over used idiom "Game changer"

To each their own of course.?

However there is so much third party support for Blender in addition to the powerful native tools and Video tutorials for users at every level that in a matter of weeks I went from total Blender newb to having my work featured in an article over at Blender nation.?

And there is an amazing free Plugin called diffeomorphic that Ports Daz content& G8 figures over to Blender with joint corrective morphs and Conversion of Daz IRay materials to Cycles for stills & animation

Many former Maxon C4D users have reported similar experiences after leaving Maxon over its subscription based model as it costs nothing to give Blender 2.9 a try.?
