habdou Posted August 19, 2017 Share Posted August 19, 2017 Hi, Does anyone know why I am getting these light highlights in my renders? This happens all the time! Thanks Link to comment Share on other sites More sharing options...
mtldesigns Posted August 19, 2017 Share Posted August 19, 2017 Could be so many things.. Is there a roof over head (for some reason keeps light from bleeding through)? Is there a cabinet light, if so might play with the Point or spot settings. It really is a trial and error. Side Note.. going to be a beautiful render once you get the light glow issue fixed.. love the back ground view out of the window too. Link to comment Share on other sites More sharing options...
Chiefer Posted August 19, 2017 Share Posted August 19, 2017 Aside from generating a roof, go to Ray trace options then lighting: -Uncheck Camera View Settings -Use Ambient Occlusion Link to comment Share on other sites More sharing options...
TheKitchenAbode Posted August 19, 2017 Share Posted August 19, 2017 Also, looks like those cabinet lights have shadows turned off, if so turn shadows on. Link to comment Share on other sites More sharing options...
habdou Posted August 20, 2017 Author Share Posted August 20, 2017 I've created a roof and and unchecked the Use Camera View Settings also had to uncheck Compute Caustics because it was getting stuck on 92% for hours even two days. This is what I am getting, still not that good. Link to comment Share on other sites More sharing options...
DRAWZILLA Posted August 20, 2017 Share Posted August 20, 2017 I think it's the light inside the cabinet bleeding through, turn it down a bit. Link to comment Share on other sites More sharing options...
CJSpud Posted August 20, 2017 Share Posted August 20, 2017 Looks much better to me. Have you adjusted the contrast yet? If not, you might give that a try. Maybe placing a light behind the camera to brighten the room up a bit would help to. Link to comment Share on other sites More sharing options...
habdou Posted August 20, 2017 Author Share Posted August 20, 2017 Hi, DRAWZILLA, The only lights that I have a part from the windows are the two puck lights under the shelve and the two pot lights in the room. CJSpud, I will try your suggestion. Thank you Link to comment Share on other sites More sharing options...

Kbird1 Posted August 20, 2017 Share Posted August 20, 2017 Judging from the light bleed around the door and window trim and Crown moulding I am thinking you haven't completed the 3D Model , eg build the Roof / foundation etc edit.... I see the 2nd pic now.... looks like the puck light angle is wrong perhaps since I see light rings on the Wall/back of the cabinet , not the shelf... at two different intensities too? uncheck auto intensity and try a small custom setting like 5% not sure why the cabinet doors are "glowing" is the wall behind the Cabinet "built" properly? almost seems like the two potlights are lighting the cabinet? or do you have User placed 3D light too?

TheKitchenAbode Posted August 20, 2017 Share Posted August 20, 2017 Looking at the current pick I think JCSpuds suggestion to add some lighting in the room would make a big difference .I believe the highlighting on the cabinets is primarily from the sunlight entering through the window, not light bleed.

habdou Posted August 20, 2017 Author Share Posted August 20, 2017 Kbird1, see attached screenshots, TheKitchenAbode, I will try a night ray trace to test it. Link to comment Share on other sites More sharing options...
Kbird1 Posted August 20, 2017 Share Posted August 20, 2017 you appear to have at least 3 different exterior walls but the pic is too small to see details and I think you have selected the wall behind the cabinet? so I am seeing a Temp. Dim. line there? not a different wall definition. Turn on the Show position in Camera view for each light so you can tell where it is pointing, it will show a red cross with a Blue end arrow so you know... try the Pucks as Spotlights not point light too , the RT will take less Time.. ( one of Graham's Tips) Do you have your Foundation Built ? weird things happen in my test plan here when I don't... You didn't lose some lights inside the cabinet did you while placing the pucks ? puck usually place with 0" offset from the ceiling..if not dropped on a wall cabinet. Graham (KitchenAdobe) is one of the Resident RT experts ... post your plan and I am sure he will figure it out.... I see light bleed around the Cabinet Door Panels , which I don't think is a Sun problem as the Sun angle appears to have changed between the Pics.... ( light coming in windows) PS Nice cabinet BTW.... Link to comment Share on other sites More sharing options...
habdou Posted August 21, 2017 Author Share Posted August 21, 2017 Thank you all, I will try again and post the results Link to comment Share on other sites More sharing options...
Chiefer Posted August 21, 2017 Share Posted August 21, 2017 All good advice. May I add. Sometimes tweaking the material property or changing color into a material like a white jpeg texture (I tend to use lighter creamy material) will solve the problem. Let me explain about the lights: Point lights are "Omni lights" (like the sun), they use soft shadows, longer to ray trace. you can turn soft shadow off to counter the long hours. Spotlights do not have soft shadows thus speedier to ray trace. New users use these to fake scenes making the surroundings brighter than usual. (Even the corners are bright) The default ray trace settings of Chief is Ideal because it is "unbiased" like Kerkythea or Corona Renderer but we already know the results...Chief can focus on this issue the next time, they are on the right track but seems don't prioritized this aspect. In the meantime, as a last resort, add lights behind the camera (no shadow) as advised or turn Environment light off. Link to comment Share on other sites More sharing options...
TheKitchenAbode Posted August 21, 2017 Share Posted August 21, 2017 In any circumstance where there is an issue or unanticipated effect there are always a variety of techniques one can develop as they attempt to counter or eliminate the undesirable effect. I tend to categorize these techniques as either ones that directly address the root cause and those that only address the negative side effects of the deeper issue. If the root cause can be successfully understood and addressed then it's negative effects can be effectively avoided from then on. Techniques that fail to directly address the root cause means that one will be constantly having to address this time and time again. Light bleed is a good example of an issue that can be fully addressed right from the get go. I will try to provide a more in-depth explanation in the "Let's Ray Trace" thread in the near future.

Kbird1 Posted August 21, 2017 Share Posted August 21, 2017 posting a copy of the .plan file is the best idea.... Graham and Jintu are both great at Raytraces so are your best bet to a fix , but they are having to guess without a copy of your plan as there are just too many variables. M.

Dennis_Gavin Posted August 21, 2017 Share Posted August 21, 2017 here is the plan ray traces with tone mapping turned off in image properties and some adjustments made to contrast and brightness. THe 2nd picture is with a couple of adjustments via Microsoft Office picture manager. Link to comment Share on other sites More sharing options...
CJSpud Posted August 21, 2017 Share Posted August 21, 2017 Nice Dennis. At least you got rid of the "light fuzz" around the crown moulding. The light in the cabinet on the right appears to be in the wrong location to me (too low). If those are wood or ??? shelves in the cabinets, I wonder how it would look if they were glass?

Renerabbitt Posted August 21, 2017 Share Posted August 21, 2017 Showing up very late to the party here but "enable environment light" in raytrace settings often times produces the light bleed effect which I'm guessing was the culprit as it is not a material setting or a photon issue and is present around areas that typically have shadows...A very common problem with environment light at its default of 1.

Renerabbitt Posted August 21, 2017 Share Posted August 21, 2017 Just to confirm(and also because I can and it's fun), photometric light analysis shows that all of the "light bleeds" are in location of low luminosity, which would confirm the environment-light theory Link to comment Share on other sites More sharing options...
Chiefer Posted August 21, 2017 Share Posted August 21, 2017 Ambient Occlusion with a max intensity of 4 or 5 will eliminate bleed throughs in no time, even with Env light value of 2. Image below at 2nd pass with almost zero bleed through. This is with env light value of 2. max intensity AO of 5. and sun intensity of 6. Link to comment Share on other sites More sharing options...
TheKitchenAbode Posted August 21, 2017 Share Posted August 21, 2017 Adjusted shelf pucks, adjusted 3D point light, adjusted image properties. Ambient Occlusion min = 0.0, Max = 1.0, Direct sun 2.0, Environment light 1.0. Everything is fine. 1 Link to comment Share on other sites More sharing options...
