Mikedk64 Posted July 19, 2018 Share Posted July 19, 2018 Hi, I have this sign in red, that i want to light up when its dark. I have tried to look around for a guide or similar, but cant find anything. Any suggestions? Quote Link to comment
markdd Posted July 19, 2018 Share Posted July 19, 2018 There are lots of ways - have you got an image you can post? Quote Link to comment
Mikedk64 Posted July 19, 2018 Author Share Posted July 19, 2018 I believe :) I have these images. The black is the frame, so it is only the red part, that i want to light up. Quote Link to comment
markdd Posted July 19, 2018 Share Posted July 19, 2018 The best and quickest way to do this is to apply a texture to the "Red" Geometry. In the transparency shader of the texture, set it to glow. Set it to emit light if you want to see some light from it on other objects and also, to give it the appearance of being solid as well, you could add matt reflectivity. In the colour shader you can either set it to "Object attribute" which will inherit the fill colour or pick another colour that you prefer. You may want the default lighting to be off in order to see it properly. If so, then you need to add a light object to the scene. It can be turned off, it just needs to be there in order to tell the default lighting to turn off. You may need to apply a much higher value than 100% in order to see your glow. You need to render in a renderworks setting, Custom renderworks with the settings down at low is best to see it quickly. Hope that works ok for you Mark 4 Quote Link to comment

Additionally, in order for the "emit light" option to have any effect, make sure that Indirect Lighting is turned on in your Render Style. 3 Quote Link to comment

Mikedk64 Posted July 20, 2018 Author Share Posted July 20, 2018 okay thanks, Could it be possible for one of you to make a file, with a similar sign (Just for illustration) and with the correct settings, textures and so? Quote Link to comment
markdd Posted July 20, 2018 Share Posted July 20, 2018 Here you go. File attached. Let me know if there is anything else I can help with... Glowing Sign.vwx 3 Quote Link to comment
Mikedk64 Posted July 20, 2018 Author Share Posted July 20, 2018 @markdd that is cool. It is exactly what i was looking for! :) Now i just need to figure out how I make a good realistic render style. Quote Link to comment
markdd Posted July 20, 2018 Share Posted July 20, 2018 (edited) As far as render styles go, it is a bit of trial and error. It completely depends on what kind of scene you are creating. If its an exterior then choose exterior indirect lighting because Renderworks won't look for a ceiling to bounce off. Otherwise, build up on the renderworks style I made in the file. Tick the various options as you need them. You will notice that I set the curved geometry to high so the curves on your sign render smoothly, and I put indirect lighting at medium so that the light from the sign renders smoothly on the surrounding box. It can become "splotchy" if the settings for this aren't high enough (however there seems to be a very welcome improvement with this over the last few service packs). Its all very subjective, and there is a really good video playlist that@Jim Wilsonmade on the youtube channel. The video below is about Renderworks Styles, but the whole series is well worth a look. This playlist is also very good. Also this video might be helpful for what you want to achieve. Edited July 20, 2018 by markdd 1 Quote Link to comment
