Hello, Yes, you can convert any resource from any tool to XP thanks to the dedicated editor. The XP editor is not yet available now, currently only the one for 2k3 is available. I am currently busy on the development of the pixelizer filter and various graphic effects.
As soon as the filter is finished, I will resume with the development of the editors like this Rpgmaker Asset Converter Tool 1.6.3 - YouTube
