  • Increase Direct Light on Object

    I am not sure if there is a way to do this already... if not I will post in the wish list forum.

    I want to increase the amount of direct light that my trees receive. I don't want anything to change in regards to GI, I only want the intensity if the direct light to be brighter. I don't want to increase the GI received because that increases the GI, I only want the direct light to increase.

    I am solving this now by duplicating the Vray sun and setting it only effect the trees.

    The obvious solution might be to adjust the material to get the look I want but it is far to cumbersome to dial in a material compared to just increasing the direct light effecting the material.

    most practical way is render a matte of the trees and do a quick tweak in post. much less fannying round with test renders.

    id imagine if you have an extra sun hitting the trees, they will kick out loads more GI onto the scene, and each other.

      Matte pass and tweak in post was my previous workflow... I find it much faster to increase the sun in the 3d scene and I don't have to update mattes when I change things. The effect on the GI from duplicating the sun is not noticeable.

      I agree on the test renders.. which is why I don't bother trying to adjust the material.

        In stead of the VraySun, use a direct light and play with the Advanced effects / affect surfaces / Contrast.
        This is the best way to plat with the direct light of how the sun hits surfaces.

        We use this for all our exteriors, specially with trees.

          If I didn't misunderstand the case, simply you can add a 2nd light that is identical to your key-light, excluding all except the trees, and adjust the direct light as you like.

            I often exclude foliage from gi - then to compensate for the dome light contribution through gi I add another light just for foliage - dome, sometimes slightly green ambient light. you would probably want to have control over its color so its better to just add another light than have a multiplier somewhere.

              I will check out the direct light option.

                This is basically what I am doing with the VraySun. It works but it requires extra steps... extra steps run the risk of a use error happening in the pipeline. I was hoping for a more efficient way to increase the direct light.
