Does anyone of you know how to make only some parts of a model glow while the others are rendered normal???
I used the code in the Glow Filter Tutorial on a textured sphere, but now the whole object is glowing…
!!!THX!!!

there is a intro.html file in the glow-example folder. it’s explained how the glow is working and how to only make some parts of the model glow ( glow-information is taken from the alpha channel of the texture)
Hahahaha…
I’m so silly!!!
I always forget to look in the most obvious places.

Hi, I am a new user on Panda3D.
sorry…I also have a question about the glow tutorial, may I ask…
As the description said, the alpha channel of the texture is used for glowing part of the model.
I found that there is a “tronally.png” texture in the glow tutorial folder. When I opened it in photoshop, it already is the glowing texture but not in the alpha channel.
Is there anything I made mistakes or do I misunderstand anything…? Thankyou for reading my text (I am not good in English ).
Photoshop moves the alpha channel into the image’s transparency mask. This is not what you want in this case. This has always driven me crazy about photoshop: there’s no way to load an image with an alpha channel. I do not know of any workaround.
In fact, I suspect that this bug in photoshop is the main reason that panda3D supports putting the alpha channel in a separate JPG.
It works for me, when loading the png and doing a decompose to RGBA.
THANKS EVERYONE
