AShadow Lib : Refractive Water Question

(Posted 2007) [#1]

Hello,

Is it possible to remove some meshes/sprites from showing on the water's refraction ?

_33	(Posted 2007) [#2]

Only if you can code the D3D clipping to do that. Or maybe I didn't understand your question. I use AShadow with reflective/refractive/fog water.

ok, i have another problem, my GUI in game is build with sprites, if I turn on Glow or blur or DOF, the effects will also work on the GUI.... I really need to find a solution to exclude certain things from being process by the shaders, but how ? :/
Any help is welcome!

_33	(Posted 2007) [#4]

Those are PostProcess effects (Glow, blur, DOF). If you do your POst Process, and THEN your GUI, you shouldn't have any problems. I use FastImage, which, I think, shouldn't have issues with AShadow.

Also, if you can set your own RenderStates, then you could probably remove the effects yourself with the proper settings.

Here. I won't show you how this works. But, you'll be able to understand what Ashadow does with these RenderState codes.

This is my func_d3d.bb that I use in conjunction with my own version of Ashadow.bb, that uses these constants. I changed all the numbers with these so I can figure out what is going on in this complex set of tools. I suggest you do the same.

Cheers.

after PostProcess render, simply use RenderEntity(MySprite) and it will not be affected by bloom, DOF or any other postproces VFX

yeah, but the problem of doing that appears when you are working with other libraries as spritecandy or similars... You cannot do 'renderentity(entity)' because that part is done by the own function of the lib...

I've worked with FastImage and it works fine.
I start to work with fastfimage for this issue...

..yup..thats truth if you are not using parent as a render entity...if you create pivot and make it parent for whole gui elements, and then using Rendernetity(CreatedParentPivot) then its will do work just fine...I tried that with Alpha GUI and its working just fine...I didnt try SpriteCandy but it should be same I think...as for FastImage, I find that its not working well on ATI cards(all sprites shown at the same time, regardless are they hidden or shown)..

Sprite Candy uses a single surface system so simply do renderentity with that one used for the UI
shouldn't be too hard to find it in the sources :)

Thats it..this settings working just fine if you put
parent of all HUD/GUI elements in to RenderEntity..
Settings you see here regarding Logo is for given resolution since I use to put it manually on proper position, so, suit yourself for some other screen size...I hope it helps..this working just fine here and none of my sprites or HUD is affected by Ashadow postprocessing /refracting if came over water, DOF, Bloom, etc/

thank you, but still it isn't working here ???

Please can you test that code on your computer, if you push L CTRL or F it will add some effects and it shouldn't right?
