Author Topic: Sprite as mask question?  (Read 211 times)

Heat Advisory

Hey guys, I made this mask sprite for an astronaught helmet, looking through.
I could see through the inside non-glass part.
I want the sprite to only let the glass be see-through, how do I do that?

Use the alpha channel.

Simply edit the sprite in any image editor other that MS Paint (I'd recommend Pain.NET) and give the desired parts some opacity.

You could have two sprites - one with the glass scratches, rendered with burnout or somesuch, and another with just the helmet sprite, with a transparent region in the middle to represent the glass part.

Alternatively, you could take the astro helmet test v3.jpg add a degree of transperancy (use a greyscale-to-alpha plugin in some photoshop software to maintain the scratches) to the glass areas.

I hope that made sense!

Cheers,

George.

I have paint.net, Can I save in dds. file format?

Also, thanks georgio123 I had an idea similar to that.

Yes, Paint.NET can save in DDS format.
You should just be able to delete the "glass" or use the transparency setting in Paint.NET and make it see through completely, or see-through-ish.
