Zerbu's Mod Constructor V4 is a powerful tool for Sims 4 that can be used to create custom traits for Sims in CAS, lot traits, aspirations and more. In this video tutorial, I'll be walking you through very basic trait creation for Sims (or cats, or dogs - you have the power!) with step-by-step instructions: https://www.youtube.com/watch?v=AwyzFW6Z13YAll credit goes to Zerbu for creating the tool. It can be downloaded here: https://zerbu.tumblr.com/post/181782526135/the-sims-4-mod-constructor-v4Advanced MC4 questions should be routed through Zerbu's Discord in the mod-support channel.

Last content update was after Island Living I think for the part-time careers.He does not have tutorials, other people do. The career tutorial is here.Some, not all. Also, he doesn't answer questions on how to make anything. It's done by other people in the server (Kuttoe is one, I'm sure you've heard of them) who are well aware that the program has issues and limitations. Appreciate the link. Tried it out and made a "P*rn Star" career. :wink: Just to test it out. Worked like a charm. Tool has a few bugs, and as stated, the tutorial is a little out of date, some things listed in it don't work at all, but I was able to figure it out. It works fairly well.Still have some things to figure out. The "Promotion Gift" thing wasn't in there but I was able to figure it out. The promotion bonus they documented in the tutorial works, but doesn't show it on the promotion notification. Still need to figure that out. The promotion text messages they list don't work at ALL. So, I just removed all the messages.It's given me a good base for building things. Just want to figure out how to do the "work-at-home" tasks, if the tool even supports that.

I'm trying to use this application to make a Trait, but I keep getting the "Only lower priority components can be added to an element while it's in the middle of being built."I'm looking for a comprehensive tutorial - initially I read there was a pdf file but I can't find it anywhere on the page where I downloaded it. Does anyone know why I'm getting this issue and what could fix it?I'ts appearing when I try to add loots...

so complicated... I'm terrible with coding stuff

How can I set custom trait to reward store, no CAS? Thank you for help.Reward traits can't be fully created in MC. You can create the beginning part but you have to eventually add additional code in S4S.https://simsvip.com/2017/10/18/create-mod-create-reward-trait/ This is old but should be helpful to you.

Is this thread (and the tool) still active? I've used it to make simple traits before, but now I can't seem to get the skill multipliers nor the relationship multipliers to work.. Does anyone have any ideas what might go wrong?
I've applied the multipliers to the core buff, and have added nothing else.

@Pat222 For further questions about Mod Constructor you should to head to Zerbu's Discord server. There are similar questions on there and you can use the search function to find an explanation on how to find unsupported interactions, or someone will explain the process to you.

It´s solved, but I have other problem. I want create my custom Eco-friendly trait, from The sims 3 Ambitions. I know create it, but I want buff for clothes line. "Saves electricity" when Sim use clothes line. I need use interaction running, but I can´t find clothes line interaction in this latest version Mod constructor v4 updated. How can I find this interaction?

@Pat222 Is it custom or an EA one? Try changing the icon you chose to another one if it's EA, and if it's custom try making it a power of 2 or switching to another image. Other issues can be missing data, so make sure everything necessary is filled. That's about all I can suggest though.

Is there a way to open this on linux? I really want to make cc and custom traits, but it doesn't open no matter what i do! It infuriates me that there's absolutely no way to make cc on linux, so can anyone help me open this?
