<div dir="ltr">Hi,<div><br></div><div>I understand the shader part of ev_pro_22 but I 'm not shure the problem is here, the shader is only used to change texture coordinates and do soft-edging. In both cases, ev_pro_22 or ev_pro_22easy, I send a texture ID. So the chain with ev_pro_22 is not the one that does the work from movie to texture (the CPU part), it's done once by another chain. </div>
<div>For what I understand, using the same texture ID for different gem chains avoids using the CPU for each chain, you use CPU only to "transform your image, movie or whatever to a texture (which is stored in the GPU memory), then each chain links to the texture ID which is the position of the texture in the graphic card's memory. Am I wrong ?</div>
<div><br></div><div>For instance, in the same work I do texturing on 200 pmpd masses linked to a gem chain. So 200 independant rendering chains, one texture, and this works without a problem. And there's no shader involved</div>
<div><br></div><div>Moreover, the texture used for masking is a only one black pixel (see the masking example), so how come this could be so heavy ?</div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">

</div>I think ev_pro__22 uses OpenGl shaders so it uses the GPU in the graphic<br>
card. ev_pro_22easy uses the main CPU to made the work, so is less<br>
efficient, but it works in older machines.<br>

Great piece of software the extended toolkit view...<br>
