Increasing the Subdivision Iterations has also helped to reduce the number of black patches on the displaced sea waves. In the example images below the ocean floor's Standard shader has an Emission Scale of 1 and a blue/green Emission Color.
In this case, the shading (Auto Bump) normal says that we are hitting the backside of the water and should reflect down, while of course in actuality the ray is hitting the top of the water mesh.Īt grazing angles, real water is nearly 100% reflective, but even so, it may take several bounces for the light to get out of the valley behind a wave crest, and even after several bounces it may reflect something that is higher up from the horizon than what the surrounding water reflects.Ī more realistic look is to make the water transparent and then place a plane below the water that has the color of ocean water. Turn Cinema 4d into your own lighting studio This tutorial shows you how to use the HDRI Light Kit Pro kit of plugins and addons to create unique lighting effects - add your own softboxes, ring lights and other sources to improve your renders. Shading normals can cause problems when the shading normal points away from the ray even though the geometric normal points towards the ray. This means that non-glancing rays will not reflect and will instead refract and go through the water (like in real life), but since it's not transparent, we instead terminate the rays and get black.
The ocean shader is not fully transparent.
