Now the real work begins. We need to find the hero's properties tree and create a new object in the Textures -> Icon128 line. Then, we save and close the editor. We open the map using an archiver. We find the xdb file with the same name as the object. We open it with a text editor and in the DestName field, we add a link to the texture, for example, . We also change the image size tags (Width, Height). We copy the dds file to the folder with the xdb file. We save. We open the map. We check if it worked.
Thank you very much for your answer!
I did as you suggested, and I found everything. Unfortunately, it didn't work; there's a white background instead of the image. When I hover the mouse over the hero, the familiar Sinistar image appears.
What can I do?
