Ventuz Forum

I'm still desperately seeking help with this :oops: By tweaking the basic HLSL node, I've solved one element of this project (a simple blue rectangle which needs to multiply the grayscale underlying layer)... float4x4 WorldViewProjection : WORLDVIEWPROJECTION; // Vertex shader program input struct V...

Looks like it will need to be an HLSL shader, and if anyone can point me in the direction of how to make this work I'd be eternally grateful! So, how do I get Ventuz to make sense of this blend function? float4 Multiply (float4 cBase, float4 cBlend) { return (cBase * cBlend); } I guess I need to def...

We do have the Texture Mixer Shader http://www.ventuz.com/support/help/latest/NodeShaderTextureMixer.html which might allow you to do what you need. Thanks for that – I will check it out. I was just about to post to say that I've not had the chance to get my head round programming my own Multiply B...

Not completely sure, but I think that's not possible with the DirectX fixed function pipeline texture shading. Simplest solution is to use an HLSL node, use the trivial vertex shader that is automatically filled in and simply do the multiply in the pixel shader. Check out http://www.ventuz.com/supp...

I'm hoping someone can help with an urgent request... is it possible to replicate the effect of having a layer "multiply" the layer beneath as in Photoshop? I need to place logos over an animated background, but rather than simple alpha transparency, the colours in the logo needs to multip...

No idea how those boards work. Could be autosensing but I always prefer hard settings so I can be sure it is always the same signal. Totally agree.... except I can't see anywhere how to fix the settings on the Deltacast side to a particular resolution. There's nothing in the Windows System settings...

You only get pinch sharp if you do a pixel for pixel mapping of the input. Otherwise like every other picture scaling in Photoshop you will have a quality reduction. Either it blurs slightly or it is so crisp that it actually produces slight artifacts. If you take an Encore or Spider video system y...

Hi! To have a pixel to pixel mapping you would need the Overlay Rectangle node. If you create your own 'overlay' you would have to shift the texture by 0.5;0.5 pixel with the Mapping 2D node (currently not sure in which direction). Best Regards Karol Thanks Carol, but doesn't the Overlay Rectangle ...

Quick question... Do I need to do anything specific when using a DVI input (Deltacast board) as a texture on a simple rectangle geometry to ensure the rendered output is pin sharp? Background: I'm using a MacPro to provide separate DVI and SDI input sources whilst building the current Ventuz project...

If you use a lot of Macs then I can easily recommend Cinema4D as it works on both platforms and is a very easy to learn and powerful 3D package. The export/import of elements with Ventuz is easy and very good. Whatever you do, do NOT use 3D Studio MAX. Of course this is my personal opinion but I th...
