If I only have a diffuse and a normal map, is there a filter or tool in GIMP that would help me create an appropriate specular map?

In this video you can see a guy creating a tillable texture, and as he draws it, it automatically displays it as being tiled.

How does he do that?  It's clearly in Gimp, and this would be SUCH a useful tool.

There is no pdb call for Exposure setting.
How do I do the equivalent?
Thank you in advance

When I install fonts from Adobe Fonts, they show up in my other programs, but not GIMP. I spent about two hours last night with Adobe customer service and we couldn't find a workaround. The guy even installed GIMP on his computer and was able to reproduce my problem, but no solution was found. He suggested I ask in online GIMP forums to see if anyone has found a workaround.

The Adobe Fonts show up in Photoshop, as expected. They also show up in Typograf, MS Notepad, MS Paint, and LibreOffice Writer, so it's not that the fonts are limited to only Photoshop or other Adobe products.

Is anyone successfully using Adobe Fonts with GIMP? Did you discover a workaround?

I'm using GIMP 2.10.38 (revision 1) on Windows 11 Home 24H2.

Thanks.

PS: I checked as I was writing this and the fonts do not appear in Inkscape, either.

I typed a text. How can I move it to another location. I click on it , try to drag it, but the layer below the text moves. And no, the text layer is selected. this is very counterintuitive.

Hi,

I am new to GIMP and am trying to master some of the simple parts of editing and saving photos. I can load and edit the photos but what I can't understand is how export straight to the Photo app on my Mac. I have looked for this in the chats and also on places such as YouTube but all I can find is ways to save to the desk top.

When I select "export as" I get the dialogue box and select A file name add the file extention I want (jpeg) and click on Pictures under the places tab. However once I click export I cannot find the photos. 

Can anybody help explain to me how it's possible to save directly to my camera roll/photo app Please? 

I don't really understand things like file structure and hierarchy so the simpler the better please.

 Many thanks
Rob

Two question, what is this closest equivalency of the "default" algorithm?  Is it similar to Fant or Lanczos?

For in game grass, flora and plant DDS textures in the range of 2k to 4k, what would be the best algorithm for mipmaps?  

Thanks

Actually it's a question from a friend, sorry if this is not allowed. 
Thanks in advance

Good day my fellow Gimpy's. I have been using Gimp for a while now (7 or so years) but only the basics and what i need to create and paint cars in iRacing. My questions, can you make a smoother curve with more nodes or less?
Second question, when move the nodes to create a curve sometimes the line disappears and i get another anchor with 2 nodes splitting out. Its almost like you have to hit that node in the right spot.

I am using GIMP 2.10.38 (revision 1). 

All the help i can get will be greatly appreciated.

P.S. Does anyone know of any videos that explain all the tools in Gimp, good videos, not those ones that play music and it`s done in 2 minutes.

Is it possible using Gimp to print a larger image across 2 A4 pieces of paper. It must be a seamless join, with a 1/4" "crossover" to enable taping paper together.
