Question by komodor · Mar 31, 2015 at 11:19 AM · windowconversionnormalmap

how unity recognizes normal map? how do i disable the conversion prompt?

hi, i am working on 2d shader and unity still bothers me that it wants to convert my height map to normal map

  1. do i need to? i am using the one channel as map i don't need normal map at all (i guess)

  2. is there way how to disable this annoying prompt? (which btw is buggy right now, because editor just didn't ask to save scene when quitting)

edit: really? nobody feels bothered by unity suggesting conversion all the time? nobody knows? i just hate that ignore button i have to push all the time

I would like to point out that its a very valid question how to disable this annoying normal map settings dialog. Now in 99% of unity user cases agreed its very handy to see this dialog. But the for the few developers who require a runtime normal map solution then this dialog really begins to be an annoyance. What the author was asking is there a way to disable these warning dialogs in the unity editor for such rarer cases. Its what makes it customisable for different types of projects.

Well, if Unity displays a warning, you most likely are doing something wrong. A shader property that is named "_BumpMap" is a normal map and need to be a texture that has been imported as normal map. If you write a shader that needs a texture and this texture is not a normal map, you shouldn't call your property "_BumpMap".

You provided no information on your shader and what properties it might have / how they are declared. Instead of adding those "attracting" tags [NOBODY KNOWS] you should improve your question, add more details.

yes i am probably using "_Height$$anonymous$$ap"

i was using bumpmap before, i thought it's by the name so i changed it but it still asked to convert it so i thought it's about the image so i asked the question

and yes i was using this attracting tag, but after long time without any answer (and i attracted you and i am greatful for the answer)

the shader is for 2d game, it's mixing some masks, applying them on handpainted maintex bitmap and then i compute the "bumpmap" but i'd say it's close to old photoshop effects like emboss or bevel

i need the shader on sprite and the sprite with bumpmap made by normals wasn't working when flipped

so in next iteration i will change the name from heightmap to something else and this should dissappear

thank you!

edit: i just realized somebody removed the attracting tag from my other posts :D i just want to say i am not putting the tag on every question and i am waiting long time before i do something so desperate like this ... and i will probably use this technique again, when i can't find answer for long time

@komodor:
Don't do something like this. You just try to elevate your question above all others. That's just selfish and not fair. Ins$$anonymous$$d try to improve your question. When you edit your question it automatically is bumped to the top of the active questions list.

Include new information you have found so far, give examples, show what you have tried already, include pictures / drawings / videos that explains your problem. If you've come here just to put out a question without doing anything yourself and just waiting (/ demanding) that someone else solves your problem, your definitely wrong on this site.

thanks for your concern but i completely disagree - the popping question is actually more selfish, because it's moving the other questions down (imagine if i pop 10 question every day/hour/$$anonymous$$ute) - my new technique attracts only people who actually look to help people with harder pieces and i used it ONLY on questions i popped few times

i understand this particular question is probably noobish and yes i am new to shaders, however i just disagree with your "selfish" classification and i will probably use it again on questions that (i believe) deserve answer

btw my questions and the answers for them are public so i am not doing this completely for myself (or at least they have side effect)

the last part of your answer is bit insulting so: i understand you got angry when you came to this question however i don't understand where did you get the idea you can edit my question and lecture me like this i use computer probably longer then you live so please!!! :D

@komodor:
First of all to answer some of your questions / concerns right away, read the FAQs especially the part about the "guidelines for writing good questions" and the next few paragraphs at least till "Other people can edit my stuff?!".

I don't see where i have insulted you o.O. I just told you about the guidelines of this site. I just said that if a question doesn't get answered after some time the reasons might be:

  • The question isn't clear enough.

  • The question is about a very specific topic and only a few people might know the answer

  • You posted it at an unfortunate time so it slipped by most people that might can answer it. (keep in $$anonymous$$d that the community is spreaded around the world and some are active when others are sleeping).

I also said that it's perfectly fine to bump the question (once a day is no problem or if it's important even several times a day). Bumping however should go hand in hand with an improvement / update of the question / progress. $$anonymous$$eep the points above in $$anonymous$$d.

(btw i started program$$anonymous$$g about 19 years ago if that has any relevance here... at least i don't see the point)

i started program$$anonymous$$g in 1982 on my first zx spectrum but that's not the point ... it's that you lecture ppl you don't even know and you edit their posts without reading them or trying to help them after you get pissed on this post
