Title: Paint tool SAI for heightmap?
Post by: Wolflover224 on November 22, 2015, 05:49:09 pm
I recently got Paint Tool SAI so I could make a heightmap for Feral Heart with it. But each time I do and convert it to .png, it either says it doesn't exist or the game crashes. Help?

Woah, the biggest mistake is to use paintool SAI, because the thing is that you cannot put it as a greyscale canvas. I recommend you to use Gimp only. Try doing it on Gimp again and tell me how it goes. Here are some tips to help you:

1- The canvas size should be 513x513
2- Grayscale canvas
3- Use the colors going from Black to white. Make sure it doesn't have a dot of yellow, red, etc.
4- Save it as .png
5- Make sure the Alpha Channel is not on. Go to Layers > Transparency and if it says 'Remove Alpha Channel' is available, remove it.

Also, make a new map in map maker. It's better to start from scratch than borrowing Watermills. Then, you can save your height map (as .png) in the new folder that will show up. It should be the name of your map.

I can't fully remember how to make sure the game doesn't crash due to heightmap.
But make sure it is 512x512/513x513. Also, try making it jpg so that the image is flat.
If I remember correctly, the heightmap won't work if there are multiple layers.

Moving this to the Game Help (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&board=24.0) section as it more revolves or belongs there.

As Preach quoted, I believe it's hardly possible to make a heightmap with Paint Tool SAI. Gimp would be a much better program and should easily work.

I made a mistake, and I didn't realize that you had to convert it to greyscale! I completely forgot!
But is it possible to convert a picture from SAI onto gimp and make it a heightmap? The reason I was so intent on using SAI was because my map has very small details that are hard to make without zooming in, and I do not believe gimp has the ability to zoom in.
Some further help with the situations above would help!

 Check HERE (https://docs.gimp.org/en/gimp-tool-zoom.html)  for a tutorial on how to zoom in on GIMP, if you need it.

I believe that you can make a heightmap on Paint Tool SAI and convert it to greyscale using GIMP. I'm not sure if this effects the quality in any way, but I've done it multiple times before and have had it working in FH so I think you can do ahead and do it too.

Just make sure to change it to greyscale and remove the alpha layer (if it hasn't already been removed), and you should be good!

You can always save the image as png and then open up Gimp. Make a new canvas and change RGB colour to Greyscale. Then change the canvas size to 513x513 or 1025x1025 (whatever size you had your map, other sizes do not work). Then you can just delete the layer made and copy and paste the height map onto gimp, so it then replaces the layer before and it becomes a greyscale image.

You will then need to Export the image as a png file and it should work.
