I think Relativity only can shorten time of sleep - I am a little bit sceptic, because I don't want to all Town get up for example at 3am...
Next one is Retuner... But i cannot find beds...
Ive also searched art-bag (street-art skill) to shorten time of graffiting - also didnt found.

Thank you in advance for your help!

I don't know how to do this with NRaas mods but here's one that might interest you. http://modthesims.info/d/413329

I'm not exactly sure what you are asking for. I use this mod to get the same energy gain for all beds: http://modthesims.info/d/413329 That mod also allows you change the energy multiplier for individual beds.

To change the energy multiplier value in Retuner for a given type of bed, click on City Hall or any computer>NRaas>Retuner>Settings>General>By Tunable XML>Sims3.Gameplay.Objects.Beds.Mimics>[choose a bed]>kTuningBed>EnergyMultiplier

Values range from 0-2.0. 1.0 is the cheap brass bed. 1.36 is the best bed in the base game (the sleep-slave double bed). The dream pod from ITF is 1.5 (the highest I've seen).

The bed names you'll see in Retuner are the "internal" names the game uses, not the name of the bed in the buy catalog. Figuring out which is which can be tough (at least I thought so). To find the internal name I used S3OC (sims 3 object cloner) to identify the bed by the thumbnail and find out what the internal name is. I don't know if you can change Store beds through Retuner. The mod I linked to seems to work for those though.

I don't know how you'd shorten the time it takes a sim to complete a street art piece.

I'll look for the street art as soon as I'l in game unless someone beats me to it. Not in game right this moment,

@Trey You can always plop down a bed and do a DebugEnabler Who Am I? on it to get it's scriptclass.

Looks like the street art stuff is table based which Retuner cannot get to.

Nice tip Chain. Thanks!

Hi! Thank you for so many replys!
So I have http://modthesims.info/d/413329 - but my program Dashboard tells me that its "CONFLICT" with nraas mods - so I wanted to fix that and maybe use just Nraas mods if possible.

Thank you!

Which NRaas mod does Buzzler's Same Energy Gain mod conflict with? Dashboard doesn't show any conflict between Buzzler's mod and any NRaas mods I have currently installed.

For the most part a conflict often means only that the mod is using the same resource. I have the mods in question and never had any problem with them.
For full details Nona Mina's Understanding Mod and CC Conflicts with Delphy's Dashboard is an excellent tutorial with illustrations. Click on the link at the top of the page I liked to and the PDF will download so you can see the original document.

Oh thank you very much. So Now I understand that if there is a CONFLICT in Delphys Dashboard it doesn’t mean it is bad. I should be more careful when it’s “CORRUPT” rather than “CONFLICT”. Am I right?

Thank you guys
